2048kb block size

[Danny Braniss]

can the da(4) handle non 512 block size? im asking because at 512 all is ok,
but 2048 does not get past geom. 

the iSCSI driver has no idea about blocksize, and seems to be doing the right
thing:
Oct  5 15:44:45 rnd kernel: da0: 10239MB (5242368 2048 byte sectors: 255H 
63S/T 326C)

what am i missing? or in other words, is there something i have to do in the
iscsi driver to fix this?
