I fully agree. This doesn't belong in the kernel. If the Windows driver
breaks someones device on purpose they should know about it, and *if*
they want they can reprogram the device using the tools mentioned in the
thread. But the kernel shouldn't be playing such games and reprogram
eeproms behind people's backs.
