6.2 SHOWSTOPPER - em completely unusable on 6.2

[Goran Lowkrantz]

To add another twist to this: I added options POLLING to the kernel, moved 
the fireware and USB drivers from the kernel and loaded them as modules. I 
have NOT enabled polling on the em-interface but this new kernal, built on 
the same sources as the failing one works without a hitch.

As before, let me know if there is anything I can do to help.

Regards,
	Goran L
