I've been very successful with a T23 and ACPI. My recipe for success
is to use the 2.6.9 kernel with no additional acpi patches added and
upgrade the bios to the most recent revision. I also have added the
ibm-acpi package for additional functionality. The ways I can suspend
now using acpi are lid close events and Fn-F4 key combinations. I've
written scripts for acpi controls and suspend scripts to suspend the
laptop with a lid close event and I found an issue on the T23 with the
earlier eepro100 driver and replaced it with the e100 in my kernel. I
also seem to have issues with pcmcia and only the orinoco card so I
make pcmcia stop at a suspend event and then restart it when the
system comes back.
My success rate with the T23 has been very good of late and I've
shared the same approaches with a few others on the ibm thinkpad
mailing list and they have been successful.
If you want my scripts and my kernel config for the 2.6.9 kernel.org
kernel, let me know. As an aside with a kernel before 184.108.40.206 I
always had to patch the kernel with the acpi patchs from acpi.sf.net.
With 2.6.9 I dont any longer.
For me and a few others the primary success thing has been upgrading
the bios to the most recent version on IBM's website.
