S1 Suspend almost working with 2.4.19 and 2.5.44 on Travelmate 360

[Phil Messenger <phil.mes-J1btbF6uMEmsTnJN9+BGXg@public.gmane.org>]

After much fiddling, I've almost got S1 suspend working on the above 
system, with one caveat:

2.4.19 and 2.4.20-(pre11 | rc1):

System suspends, backlight isn't turned off. System resumes and is 
active on the network, so I can SSH into it, but the keyboard and 
touchpad apparently aren't reinitialised properly and won't respond. 
Note that the system hasn't hung, but the keyboard and mouse are "frozen".

2.5.44:

System suspends, backlight isn't turned off, system resumes and is 
active on the network. The keyboard is again hung, but if I cycle the 
input drivers (rmmod then modprobe i8042, atkbd) it responds again. I've 
actually written a small script which turns the backlight off using 
DPMS, suspends the system, then cycles the input drivers on resume. I'd 
much rather use 2.4 though - PCMCIA is utterly broken on this machine in 
2.5, wheras it's only a bit broken in 2.4.

Is this a known problem? If so, are there any work-arounds? Or if it 
isn't, is there anything I can do to help debug it? I don't know much 
about ACPI and the Linux implemntation and I don't have enough time to 
sit down and understand it so I'm not sure where to start...
Cheers,

Phil.
