Subject: [BUG] via c3/2.6.20 -- ps/2 keyboard doesn't work with console

Hi,

I'm trying use the 2.6.20 kernel and have run into a problem using the
ps/2 keyboard with console. When I type input in response to console
output the characters aren't echo'ed and the console program doesn't
receive the character input. It seems like the problem is specific to
the ps/2 interface because a usb keyboard works fine.

Here's dmesg output:
