I think modern kernels will do this for you if they detect a Thinkpad. 
My machine (a 600) does this (stock RH 7.3, no kernel recompile):

kernel: IBM machine detected. Enabling interrupts during APM calls.

$uname -a
Linux tycho 2.4.18-3 #1 Thu Apr 18 07:37:53 EDT 2002 i686 unknown

It seems that the right option is enabled whether you recompile for it or
not.  The .config redhat doesn't:
[...]
# CONFIG_APM_IGNORE_USER_SUSPEND is not set
# CONFIG_APM_DO_ENABLE is not set
# CONFIG_APM_CPU_IDLE is not set
# CONFIG_APM_DISPLAY_BLANK is not set
CONFIG_APM_RTC_IS_GMT=y
# CONFIG_APM_ALLOW_INTS is not set
# CONFIG_APM_REAL_MODE_POWER_OFF is not set
[...]

I 95% of the time tell my laptop to hibernate, as my battery's going bad.

No suspend/hibernate/resume problems so far on this laptop, except:

I can't hibernate when a PCMCIA card is physically in the slpt.  It
"boops" and won't even attempt to hibernate.  Not a real problem,
though, as I have to take the card out to put my laptop in its bag.
