I know that "me toos" are of limited use, but I have also been experiencing this problem. I can give some specific details, and on request am willing to work to produce additional diagnostics / test patches etc. I am using a Toshiba Satellite 2410-603 with a P4 M processor, and I have experienced difficulties with Gentoo-patched 2.6.3 sources, Gentoo-patched 2.6.5 sources and vanilla 2.6.6 sources, with CONFIG_PREEMPT both on and off. Of the three, 2.6.3 seems the least affected - although I do get occasional keyboard lockups, if I use the mouse for a few seconds the keyboard becomes re-enabled. On both the 2.6.5 and 2.6.6 kernels a keyboard lockup seems permanent, although I haven't tried leaving it for more than a minute or two. I too can see warnings from atkbd.c in the kernel messages (on all three kernel versions) reporting 'Unknown key pressed' and 'too many keys pressed'. I am well aware that Toshiba keyboards are buggy - under 2.4 kernels I experienced multiple key event problems, so I think what's being asked here on this thread is not that the keyboard driver be "fixed" as such, but that, if possible, it is extended to work around the buggy hardware.
