As I said, I use a Medion MD 42200. However, it seems like they share a lot with those Acer laptops. Another theory might be that my keyboard is dying. I'll check that against my Gutsy CD. As I said, the keys not working are LeftArrow, DownArrow, PgDown, Backspace, Delete and Return. However, Backspace and Return do work if pressed together with Shift while all the others work with Ctrl pressed.

By the way: This happens in GRUB already.
