I found out that reloading atkbd.ko remotely over an ssh session returns
the keyboard back to normal. What is left:
o the fan seems to turn like wild after resume (echo 0 >
  /proc/acpi/CFAN/state does nothing) -- no, it isn't due to the
  temperature nor system load
o DMA must bu turned off for S3 resume (strange, it works with S4 in 2.4.x)
o kernel finds crond and acpid disturbing, and refuses to suspend while
  those are running

I might not have time to try and fix it by myself right now, so I'm
basically notifying you about these problems. Thanks for the support,
Best regards,
