[ltp] suspend resume works fine for short suspends - fails for longer suspends

I have a T40 running debian testing  APM, kernel 2.6.4

suspend/resume works fine if i test it out 20 times quickly (up to about
30 minutes delay between suspend and resume)

but if i leave the machine suspended overnight it invariably fails to
resume - the backlight comes on and i get the garbage screen i usually
do right after resuming but even the magic sysreq keys do nothing.

i noticed yesterday that while it's suspended i'll hear a beep as the
computer does something... i suspect this is the trouble.
I looked in the bios thinking that it was the redisafe option - that's
disabled.  Hibernate by timer is also disabled...
i have bios 2.11 1RET84WW and embedded controller version 2.04 

Any suggestions? - this is extremely frustrating...
