I adore those machines.  They differ only in that the 'p' has an ATI
video chipset, while the base model has Intel video.

The 'intermittent' bit is what makes it odd.  Otherwise, what I would
have said is that suspend (and ACPI in general) is sometimes twitchy
with particular combinations of laptop firmware and particular Linux
kernels.  Often, the best place to start with Thinkpad problems is on
applicable pages of Thinkwiki, such as 

http://www.thinkwiki.org/wiki/Category:T61p
http://www.thinkwiki.org/wiki/Problem_with_display_remaining_black_after_resume

I see no magic bullet, there, so personally what I'd do is see what
happens with a stable-series kernel.org kernel.  (Ubuntu like most
distros provides somewhat modeified 'vendor kernels'.)  And yes, I do
mean sitting down and compiling a kernel.  It's not difficult and is a
useful learning experience.  (Use make-kpkg,
https://help.ubuntu.com/community/Kernel/Compile.)  And you might was
well blend in the TuxOnIce patch, while you're at it:

Just make sure you retain the GRUB stanza for your existing kernel(s),
so you are immune from burning your bridges.
