Didn't find hardware. Did you hardcode the address or leave it at zero to 
auto-probe? Common mistake is to give the segment address not the real 
address (0xd800 not 0xd8000). You do need the extra zero.

Note to self: Hide that option and the 55AA one inside if(LINUXBIOS).

They changed the major number from the temporary one they were using. But
rather than using the one I'd already registered, they started using an
entirely new one. Major 100 I think.

Geometry info is useful though - can you compare it with what the free 
driver reports, when you get that working?
