How to dump video-bios (here on 2.6.36 upstream-kernel)?

# lspci | grep "VGA compatible controller"
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon RV250 [Mobility
FireGL 9000] (rev 02)

# find /sys/ -name rom | grep 01:00.0
/sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/rom

# echo 1 > /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/rom

# cat /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/rom >
/tmp/vbios_rv250.bin

# echo 0 > /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/rom
