Bug 441465

I suspect this is due to the du-kudzufication of rhpxl? kudzu has special cases
for virtual framebuffer devices, such as the PS3 and Xen.

The PS3 framebuffer shows up in HAL like this:

udi = '/org/freedesktop/Hal/devices/ps3_system_bus_ioc0_01'
  info.linux.driver = 'ps3fb'  (string)
  info.parent = '/org/freedesktop/Hal/devices/computer'  (string)
  info.product = 'PS3 Device (ioc0_01)'  (string)
  info.subsystem = 'ps3_system_bus'  (string)
  info.udi = '/org/freedesktop/Hal/devices/ps3_system_bus_ioc0_01'  (string)
  linux.hotplug_type = 2  (0x2)  (int)
  linux.subsystem = 'ps3_system_bus'  (string)
  linux.sysfs_path = '/sys/devices/ps3_system/ioc0_01'  (string)
  ps3_system_bus.id = 'ioc0_01'  (string)

You probably don't want to rely on that though; if you don't find any other
video cards and if /dev/fb0 exists, just use it.

Fix for this (I hope) built as rhpxl 1.4.  Please test, and reopen if this isn't
resolved.

I'm not sure that checking all HAL devices for 'info.linux.driver' ends with
'fb' is really the best way to achieve this. In some cases, the framebuffer
device might not be known to HAL -- it's just a coincidence that it is on the
PS3. I suspect it isn't for Xen framebuffer. It would be better to look for
/dev/fb0 or in /proc/fb, surely?

Also, X doesn't seem to be working anyway (with no xorg.conf)...

Re-fixed in rhpxl 1.5.  The segv when running without a config file should be
resolved in xserver 1.4.99.901-19, afaik.
