What version of apmd? My says "apmd version 3.0final"

You might want to call IBM to check if there's a more recent bios upgrade
that you can get. Check for T21 at the IBM site below ...

 http://www.pc.ibm.com/support?lang=en_US&page=brand&brand=IBM+ThinkPad

Look for T21 under the device driver file matrices.

(Fix) Hang up occurs when suspend/resume is done on a ThinkPad
with HDD adapter without a hard disk drive in the ultrabay 2000.
(Fix) ACPI compatible Linux hangs up at boot timing.

My /usr/src/linux/.config ...

# CONFIG_ACPI is not set
CONFIG_APM=m
# CONFIG_APM_IGNORE_USER_SUSPEND is not set
CONFIG_APM_DO_ENABLE=y
CONFIG_APM_CPU_IDLE=y
# CONFIG_APM_DISPLAY_BLANK is not set
# CONFIG_APM_RTC_IS_GMT is not set
# CONFIG_APM_ALLOW_INTS is not set
# CONFIG_APM_REAL_MODE_POWER_OFF is not set

I don't know whether the above will help or not, but it's worth a try.
