After some frantic kernel building I've more interesting data (with i8042 and atkbd built into the kernel).
2.6.2-rc1-mm1 will APM suspend and resume fine at first with the following log:
atkbd.c: Unknown key released (translated set 2, code 0x7a on isa0060/serio0). atkbd.c: This is an XFree86 bug. It shouldn't access hardware directly. atkbd.c: Unknown key released (translated set 2, code 0x7a on isa0060/serio0). atkbd.c: This is an XFree86 bug.

The atkbd lines are interesting as I was not running X at the time. The MCE line slightly worries me, is this normal?
However, I cannot sleep once I've used PCMCIA (with yenta_socket). Instead of sleeping it locks up. I didn't notice this the first time and came back to a very warm laptop, it felt like it had been busy-looping.
I was very excited by the changelog for 2.6.2-rc1-mm2 with its "updated ACPI" so I tried that. ACPI still hard-crashes (grey screen, power button dead, I had to remove the battery) and APM also crashes: it looks like it is suspending (screen turns off and there is some disk activity) but it never sleeps and I can't resume without holding the power button (so at least *something* is still running).
Summary: something regressed over mm1 to mm2 with APM suspending, and yenta_socket or cs isn't handling the suspend correctly. Does anyone have any ideas where I can look for these?
However, I did manage to use 2.6.2-pre1-mm1 for a day before I used my wifi card, and did like what I saw -- the new scheduler makes GNOME more responsive when I've a compile going.
