So how about sending in a small patch to the GNU folks that fixes the
userland crashes for starters? I guess compiling the NetBSD kernel with
a separate toolchain isn't that bad. It sure needs to be resolved
finally, but getting a working userland does have a higher priority ;-)

After some debugging: there are actually two bugs in the gsfb driver:

- In the function `gsfb_set_cursor_pos', there's an off-by-one bug which
  draws the cursor at 7x15 instead of 8x16 (can be fixed by removing the
  '- 1's from the source. Anyone with a commit bit in here? ;-)
- The `gsfb_cursor_cmd' array contains some faulty data which garbles up
  the top rows when repainting the cursor. I don't have a clue how the
  Playstation 2 video chip works, but I know the bug is there - when I
  disable the entire cursor code, my terminal works 100% correctly.
