The "T42p" label appeared on a number of different models (2373-xxx,
2379-xxx, etc.).  And they have varying motherboards, peripherals, etc.
So, you have one that doesn't need the S3_bios bits.  Consider yourself
lucky!  ;-)

Theres actually two versions: swsusp and swsusp2.  The former is in the
main-line kernel but is more-or-less moribund and the latter is an
improved approach that has not yet made it into the official (Linus')
tree.  Swsusp2 will probably be included before long since its popular,
actively developed, and its authors are trying to clear the remaining
hurdles for inclusion:  http://www.suspend2.net/

And in regard to the lockups, what kernel are you using and are you by
any chance using one of those USB-key-type flash drives?  A number of
people have had lockups with them:

and supposedly its fixed in more recent kernels.  I had a few odd
lockups with 2.6.11-1.14_F3 and have had none with the 2.6.11-1.20_FC3
kernel available at:
