Description of problem:
This is a popular model laptop and as such should be targeted for full support
asap. Of course this is not including the winmodem. But having to patch my dsdt
to get acpi working is a bummer.
See this link for an example of the trials necessary to get Linux running...
although once it's running it runs great!
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Install Red Hat Linux (any)
2.Work on your Laptop after strugging to configure X due to the uncommon screen
3.Watch your laptop overheat and battery power not hold up due to improper power
Have you tried the latest kernel from rawhide ?
It has updated ACPI, and the Speedstep-ich cpufreq module.
Yes, I think it is due to Dell's BIOS being Blacklisted... the DSDT needs to be
patched in order to get ACPI support that works... I'm just suggesting this be
included in any upcoming releases.
why is it being blacklisted ? If its because its pre-2000, you can override with

Interpreter Fix Dell's code incorrectly assumes that all arguments are passed
by reference, when they are actually passed by value. There are two methods
affected by this, so they have been modified to explicitly pass references.
It has been removed from the blacklist apparently but the bios is buggy... a
patch is still needed to get it to work correctly...
see this site
No updated BIOS available ?
Yeah, Kernel 2.4.22 seems to be running smoothly with default acpi and patched
cpufreq with an updated bios. Still no support for volume keys other than acme
(a good userland solution but only with GNOME and XFce4 with work)... also,
i8kutils required for fan control...
Kernel 2.4.22 vanilla sources... not red hat version but they should be the same
minus red hat's tweaks.
