I don't know why your kernel source is out of sync.  I will have to
go pull down the 2.4.5 and 2.4.6 trees and see if some portion of
my patches never made it into those trees.  It also looks like the
comment section for this option didn't make it into my 2.4.4 and above
patches.  I'll correct this on this on Monday.  Here's the relevent
info.  Do you have any comments on what would make it more useful?

It is hard to make the kernel driver give a reasonable message for every
possible error that running with incompatible components may cause.
