On this page you mention that Mandrake includes this patch, but your
driver (link on the above patch) differs from Mandrake one. In patch I
sent to Mandrake I just fake drive capacity in case
CAPACITY_NO_CARTRIDGE is returned.

Currently grok_partitions() silently ignores any media with size == 0,
irrespectively of whether removable is set or not. It means that *no*
entries for drive (either disc or part?) are created at all and there is
nothing that later on triggers revalidation.
I still believe grok_partitions() should create disc node for removables
even if current capacity == 0 (that for removable just means there is no
media inserted). Then it would work the way you describe and faking
drive capacity for empty drives could be removed (IIRC it happens for
other removables like SCSI disks as well).
