Others to add to the list, behaving strange with ACPI:
Panasonic CF-M34: Kernel Panic, acpi=off works, but no poweroff then
Panasonic CF-71: same as above
Both tested with TC 3.4.1 and 3.5, TC 2.9 works.
HP Omnibook 900B: Fan will run forever with ACPI, never without.
I did not manage to "plant" a kernel with working apm module yet, so I hope you will include it in TC4 when no kernel update occurs in 3.x.
BTW, in the meantime I installed TC3.4.1 successfully on an old CF card in my Lifebook B110, and it seems to work very good. A step I would recommend especially to users of older hardware, at least for the system partition. I hope that the mail-ordered faster UDMA CF card will arrive soon.
