Sorry this is a couple of days old but I have been messing with ACPI on Thinkpad T20, & T21's for months and have some observations... -Tried disabling ACPI to but now I use "acpi=force" and it seems to work better ( initialization at power-up below). -OS is Debian (testing) initially built off Knoppix 3.6 with kernel 2.6 option booted - then installed to HD with knx-hdinstall. Now running kernel 2.6.7 . In general it works quite well after alot of twiddling. Some drivers updated from the IBM ThinkPad site. http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-4JSQHB ; I cant seem to find IBM's drivers for Linux on the site now... -Finally got full functionality from the Mini-PCI modem after loads of trouble. Here is some info from dmesg related to ACPI initialization: 1 Linux version 2.6.7 (root at Knoppix) (gcc-Version 3.3.4 (Debian 1:3.3.4-3)) #2 SMP Wed Jul 28 04:25:36 CEST 2004 2 BIOS-provided physical RAM map: 3 BIOS-e820: 0000000000000000 - 000000000009f800 (usable) 4 BIOS-e820: 000000000009f800 - 00000000000a0000 (reserved) 5 BIOS-e820: 00000000000e0000 - 0000000000100000 (reserved) 6 BIOS-e820: 0000000000100000 - 0000000017ff0000 (usable) 7 BIOS-e820: 0000000017ff0000 - 0000000017ffec00 (ACPI data) 8 BIOS-e820: 0000000017ffec00 - 0000000018000000 (ACPI NVS) 9 BIOS-e820: 00000000fff80000 - 0000000100000000 (reserved) ... 17 IBM machine detected.

Apt is just a front-end for the packaging system, and there's a version of apt for RPM based systems.
