One thing that you may already know, but that was critical for my
T41p, was to build the kernel with "Local APIC support on
uniprocessors" disabled entirely.  I don't know if that's still
necessary.

In case it helps, the arguments I pass to an essentially unmodified
2.6.11 kernel are:

  root=/dev/hda2 resume=/dev/hda1 acpi_sleep=s3_bios notsc ro

I'm not certain that all of these are still required, and of course
this I have a different machine, but suspend to disk works just fine
nearly all the time.  The only difficulty I ever have is that
occasionally it takes a *very* long time to write the data to disk.
It's rare, but it happens; the disk light flickers very quickly but
faintly during the whole process.  Most of the time suspend to disk is
more than fast enough for my purposes.
