I came across a USB flash reader that has broken mode sense.

sd0: 124 MB, 678400 cyl, 4 head, 0 sec, 512 bytes/sect x 253952 sectors
sd1: 0, 678432 cyl, 4 head, 0 sec, 512 bytes/sect x 0 sectors
[...]

If the following workaround is ok, I will commit it.   

sd0: 124 MB, 124 cyl, 64 head, 32 sec, 512 bytes/sect x 253952 sectors
sd1: drive offline
[...]
