Please attach your X config file and log file

It is related to the swcursor option :

log for SW cursor

XFree86 boolean config file options may be specified in many different ways,
all of which are equivalent to each other.  The mouse cursor always defaults
to hardware cursor unless otherwise specified.  Also, case is insignificant
and whitespace and underscores are removed and ignored.  An optional boolean
indicator may be present also.

So..

Option "hwcursor"  is the same as  Option "hwcursor" "on" which is the default
anyway, and also identical to:  Option "swcursor" "off".

Rather than deal with the various plethora of ways of stating the same
thing in the config file...  no specification gives hardware cursor, and
to get software cursor, a simple:

Option "swcursor"

is sufficient.  I thought I'd clarify that just to save you from having
to poke around at what is rather overcomplicated for what it needs to be.
I dunno why they made it so complex.  I prefer to keep it simple though.

Your chart above indicates that you only observ a bug when the hardware
cursor is being used.

In Red Hat Linux 8.0, the hardware database configures this video card
by default to disable the software cursor as it is known broken.  If you
are using Red Hat official configuration tool redhat-config-xfree86, it
will have configured this properly by default.  Here is the default
settings from the hwdata Cards database used to configure the card:

NAME SiS 6326
CHIPSET SiS6326
SERVER SVGA
DRIVER sis
LINE       Option "swcursor" # Enables software mouse cursor workaround
LINE     # Option "NoAccel" # Use this if acceleration is causing problems
LINE     # Option "fifo_moderate"
LINE     # Option "fifo_conserv"
LINE     # Option "fifo_aggressive"
LINE     # Option "fast_vram"
LINE     # Option "pci_burst_on"
LINE     # Option "xaa_benchmark" # DON'T use with "ext_eng_queue" !!!
LINE     # Option "ext_eng_queue" # Turbo-queue. This can cause drawing
LINE                              # errors, but gives some accel
NOCLOCKPROBE

So technically speaking, we are configuring the card by default correctly.
Do you not get software cursor if you run redhat-config-xfree86 --reconfig
and do not personally modify the config afterward by hand?

See bug #78367 for more related info.
It was set up for HW cursor at installation and then switched to SW later.
I will try to reproduce it again.

We believe this issue to be resolved in our currently supported
OS releases.

Please upgrade to Fedora Core 2 or later, and if this issue turns
out to still be reproduceable, please file a bug report in the
X.Org bugzilla located at http://bugs.freedesktop.org in the
"xorg" component.

Once you've filed your bug report to X.Org, if you paste the new
bug URL here, Red Hat will continue to track the issue in the
centralized X.Org bug tracker, and will review any bug fixes
that become available for consideration in future updates.
