C2 or C3 on Presario 2110US?

[Carl Thompson <cet-GxmFRYwVNOxKOnpN5g9PlQ@public.gmane.org>]

     I am resending this because I got no responses to my original
message from the ACPI team on this issue.  I would really apppreciate it
if someone could let me know if this is something that is being looked
at, will be looked at or will never be looked at!  Actually, any sort of
acknowledgement would be nice.  What ever happened to the talk of
implementing a bug tracking system?

     If there's any other information I can provide or anything I can do
to help please let me know.  I am also willing to try to help more
actively if someone can tell me what information I need and where in the
ACPI code it is handled.

Thank you for responding,
Carl Thompson

Hello,

     I just upgraded my laptop to a Compaq Presario 2110US and am
pleased to report for the most part Linux ACPI works excellently on it
(without the problems I have on my Sony Vaios).  The one exception is
that Linux ACPI does not have any processor support for it (everything
in /proc/acpi/processor/CPU0 reads "<not supported>" except power which
tells me that only the C1 state is available.  I believe the problem is
that the chipset used in the laptop is reasonably new (ATI/ALI combo),
in particular the ATI bridges.  Is there any effort to get ACPI working
on this chipset?  In particular I would like to see C2 or C3 because the
2110 has the loudest fan I've heard on a laptop.  I am willing to help
in any way I can and here is the output of lspci:
