This is a simple patch so that grub-install can install onto devices 
with names like /dev/ub[a-z] (this looks as if it's going to be the 
normal name for usb devices.)

The current of 2.6.9 kernel (on sid) uses this naming scheme, so if you 
want to make a bootable USB device, it fails to allow you to install 
grub on /dev/ub* named devices.

I also had to comment out a check for errors around line 480:

+#    if test $count -eq 0; then
+#      echo "The file $file not read correctly." 1>&2
+#      exit 1
+#    fi

since I get the error when installing:

Error 18: Selected cylinder exceeds maximum supported by BIOS

However, this doesn't seem to keep grub from installing correctly on the 
usb drive.

Thanks,
Jeff

PS: is there a way to turn off the grub installer from always making the 
"recovery mode" entries for every kernel? It would be nice if grub just 
had a checkbox or keystroke that automatically would toggle appending 
"single" and instead display something right on the main screen.
