Similar problems, resolved with an upgrade to kernel 2.6.32-21-generic.

Initial experience: upgrading from 9.04 to 10.04 resulted in frozen
keyboard/mouse on starting X11. Only exit was a hard boot (no serial
console or remote system from which to ssh in).

System is a Lenovo T61 laptop.

Experimenting with rescue boot showed that system was responsive to
keyboard at BIOS, GRUB, and pre-X system session.  Booting single-user
root mode it was possible to start X session, at which point recovery
from X was not possible.  Tricks such as:

startx /usr/bin/xterm -geometry 1680x1050 -- vt12 & sleep 10; chvt 7

(where 1680x1050 is my laptop display geometry)

This would switch back to a non-X virtual console, from which keyboard
and mouse were responsive (generally killing X at this point was a Good
Thing).

I did manage to get mouse response under a 2.6.27-11-generic kernel by
modifying /etc/X11/xorg.conf to specify a mouse device:

Section "InputDevice"
        Identifier      "Configured Mouse"
        Driver          "mouse"
        Option          "CorePointer"
        Option          "Device" "/dev/psaux"
        Option          "Protocol" "ImPS/2"
        Option          "Emuate3Buttons" "false"
EndSection

... but wasn't successful in specifying a keyboard configuration (what
*IS* the default PS2 keyboard device?).

On a suggestion from irc://irc.freenode.net/#xorg, I upgraded to latest
available kernel.  Keyboard/mouse functioned with a default xorg.conf.
