It's like this:
No matter what the kernel (2.6.28 to 2.6.32-rc7), the emagic a6|2m
card just doesn't want to play along with the rest of the OS. Haven't
got the foggiest, really - tried so many suggestions, all to no avail.
This is the part of dmesg where things get hairy:

As for physical indicators (apart from the absence of sound /
inaccessibility of the card) - well, the red led lights up instead of
the green ones, and it stays lit. Under normal circumstances it is
supposed to flash up for a few seconds before it is replaced by the
green leds, which indicate that the firmware is loaded and the card is
functional. What could possibly be wrong? So utterly exasperating.
Mick, a headache and a half.
