I'm using gentoo, kernel "suspend2-sources" (a gentoo package, which
is the kernel.org kernel plus gentoo's patches plus swsuspend2
patches).  I'm using the "hibernate" and "hibernate-ram" scripts.

Generally, the problem isn't with waking, it's with suspending.  For
suspend-to-disk, when *usually* happens is the screen goes blank
(totally black), the "moon" light starts blinking, and it just stays
like that forever (moon light still blinking).  The machine is
totally hard-locked: caps lock doesn't work, ctl-alt-delete doesn't
do anything, nada.  I must push and hold the power button to shut
down the machine.

With suspend-to-ram, it's a mixed bag.  Most typically, the screen
goes blank, then the moon light starts flashing, then those other
two lights (the caps lock light and the other one) start blinking
simultaneously.  Machine is hard-locked as described above.

I'm suspending using the hibernate scripts package ("hibernate" and
"hibernate-ram").

I'm not opposed to changing distros.  That's why I was hoping I
could catch someone on this list who has all this working.  I want
to run Linux on this machine, but more than that I want to actually
*use* it.  Generally I'm not opposed to trouble-shooting/trial and
error, but all that is keeping me from being able to do real work on
the T43.  So I'm basically at the point now where, if I can't get
this working in less time than it would take to put Windows back on
and install Cygwin, then I'll just take the latter route.

Thank you,
Matt
