Greetings. 

I have been running nicely on my presario 2800t for a while, but with
kernel 2.4.18 and a pretty old acpi version. 

So, what better to do on a lazy sunday than try and upgrade to
2.4.21-pre4 and the newest acpi? :) 

I pulled down the 2.4.21-pre4 kernel. Applied the
acpi-20030125-2.4.21-pre3.diff.gz diff to it. 
Then applied the patch-acpi-acpi20030125-swsusp18.gz software
suspend+acpi patch to that. 

First I tried just compiling that and seeing how acpi would work. 
It came up, but of course with no battery/ac, etc due to the broken
compaq dsdt. 

So, I pulled down acpidump and iasl-linux-20030123.tar.gz
dumped out the dsdt and tried to compile it. 

56 errors. 

I first fixed all the "String must be entirely alphanumeric" errors
(compaq seems to like putting * in all their names.)
I realize it's against the spec, but could something be added to
change * to nothing if it finds it in a Name? 

Fixing those got me down to 21 errors. 
(Worth noting that at this point with the old iasl I was using with
2.4.18 there were no further errors here). 

Any ideas on any of these:

My dsdt.asl is located at:
http://www.scrye.com/~kevin/acpi-2003-02-09/dsdt.asl

Most of those look like thermal handling issues. 
Commenting those problems out or telling iasl to ignore them for now,
I stick my custon dsdt.hex file into the 2.4.21-pre4 kernel and boot
and I get: 

tbget-0273: *** Info: Table [DSDT] replaced by host OS
tbrsdt-0208: *** Error: Invalid signature where RSDP indicates RSDT/XSDT should be located
RSDT/XSDT signature at 2FFF0C84 (2fff0c84) is invalid
tbxface-0085: *** Error: acpi_load_tables: Could not load RSDT: AE_BAD_SIGNATURE
tbxface-0115: *** Error: acpi_load_tables: Could not load tables: AE_BAD_SIGNATURE
Unable to load the System Description Tables

Anyone have any ideas on the problem there?

Back to 2.4.18 for now I guess. 
Any help or pointers would be appreciated.
