That's a new one for me too.

Well, you could patch your kernel to use 512 as the sector size
whenever the device says 1 byte.  But you'd probably prefer to fix the 
device -- which means updating its firmware.

The manufacturers may not be aware of this problem, though.  Perhaps 
they'll point you to a fix if you inform them.
