Had the same key repeat problem on edubuntu 6.06.1
On an underpowered compaq pres with amd k6
Was unable to even enter user name etc
switched to terminal log on.
entered as root.
ran
rmmod acpi_sbs
rmmod i2c_acpi_ec
as sudo.
Problem solved for now.
I had a same issue with ubuntu under kde but not gnome
