No, grub handles this fine.  The grub device.map just tells the
grub-install script which device in /dev to open and what BIOS drive to
treat it as where (hd0) = 0x80, (hd1) = 0x81, etc.  If the first scsi
disk is mapped to /dev/sdb, but it is in fact the boot disk, then the
above device line works fine as it has grub write the various boot stage
binary bits to /dev/sdb and causes the binary bits to ask for bios
device 0x80 when actually used to boot the machine.
