I found something.  In /usr/src/linux/make menuconfig - under the APM 
setting, there's an option called "Allow interrupts during APM BIOS 
calls", which my kernel has excluded.  The 'help' says:

"CONFIG_APM_ALLOW_INTS: Allow Interrupts during APM BIOS calls
Normally we disable external interrupts while we are making calls to the
APM BIOS as a measure to lessen the effects of a badly behaving BIOS
implementation.  The BIOS should reenable interrupts if it needs to.
Unfortunately, some BIOSes do not -- especially those in many of the newer
IBM Thinkpads.  If you experience hangs when you suspend, try setting this
to Y.  Otherwise, say N."

Sounds like a good thing to try.  So is it possible to add it to my kernel
(it's not modular) without recompiling the whole bloody thing?

(By the way, I'm not using ACPI.)
