: Jesus's analysis sounds 'possible.'
: the driver under 1.x does get some information from the cmos..
: have you the correct information in the cmos setup?

: I doubt this is what's wrong however because your error sounds 
: sporadic and not at all repeatable, which whould not be the case
: if it were trying to use the wrong geometry
: (in which case it would fail the same way each time)
: it Is possible something else is making it go wild,

I would do this if I could find the 1.0 fd.c. Anyone have it?
If you do, I would appreciate a copy.

I can recompile a kernel on my machine at home and include this
old file (assuming that it will work). Were there a lot of changes
to this driver since then?
