+This programmer module supports parallel flash up to 64KiB, attached to Matrox graphics cards. The ROM BAR
+is used for reading
+.B and writing
+the flash. Because the whole BAR register is disabled by default, though, it's likely that we have to
+configure it ourselves. The ROM BAR decoding takes precedence, so we can borrow the MMIO BAR address,
+but have to make double sure that no graphics driver is running. Hence, this borrowing has to be explicitly
