Interesting, it freezes after this too:
kfreebsd (<tab>
→ kfreebsd (hd0,
kfreebsd (hd0,1<tab>
→ kfreebsd (hd0,1)
another tab, and it freezes.

With my scenario, I had removed *all* 「set root=…」 commands from the
configuration. A working one (sans replacing vga= with gfxterm stuff)
is attached, using grub from the Grml 2009.10 “Hello-Wien” edition. Is
there something you special-cased when handling CDs or not-CDs? (For
example, grub-legacy doesn’t handle iso9660 from media with !2048by
sectors at all.)

Hm. Even with grub.cfg renamed into xrub.cfg (so no config at all)
it freezes. Weird.
