ok, i know ... but it would be IMHO the cleanest solution.

ok, i've to deal with development version of hardware, which means there a
some firmware releases expected during driver development. this means i have
to recompile the driver every time i've to download a new firmware.
AND it will bloat the module itself. so otherwise i'd just pass it from the
file directly to the hardware.

yup, i know them - Alan mentioned it.

ok, if everyone agrees including the firmware into the module at compile time
would be the ultimative solution, i will quit my questions of how to do it
my way - i will use the classical way.



PS: never use netscrap mail ... i completely shot my loc;al maildir, so i got this
reply out from the news. :(
