I have a 755CD where having a working suspend/hybernate is more critical
since you need to use at least suspend to swap between floppy and CD-ROM drives.

I actually have my system working "reliably" with suspend or hybernate so
long as 

a) I turn off the 3com PCMCIA ethernet card before hybernating (usually I
don't have to do this for suspend)
b) I make sure the cover is open before I suspend if I was going to open it
anyway (say to change a drive)
c) I pull the power connector or turn off the power to the power supply
before hitting the suspend or hybernate icons.

Then these glitches still occur:

1) Sometimes (?not always) putting in the CD-ROM drive after suspend locks
up the mouse (either glidepoint or trackpoint). This is assuming I am
swapping from floppy to CD-ROM. It doesn't seem to lock up going the other
way around (from CD-ROM to floppy)
2) The battery state goes a little haywire. When I plug power back in, the
battery wants to discharge even though it is 99%, and the hours remaining
often goes into the flashing (8.88) mode. 

All of this is under WIN95. I can live with most of this (except the mouse
locking up) to save the rather excessive time of doing a reboot each time I
have to move the machine.

I think I have the latest BIOS (I think it is 1.40 needed for WIN95), and
that didn't seem to help. Also, hybernate seems to do a suspend, so if
suspend works, hybernate generally will too, except for those devices that
can't reliably be powered down (PCMCIA cards that don't quite plug and play).
