Hi Stephen,

This looks like an issue I reported previously. After you use a recent skge, 
you can't use any older drivers or the windows driver, but skge still works 
fine every time.

The Gentoo bug report is here:

	http://bugs.gentoo.org/show_bug.cgi?id=100258

I closed the Gentoo bug as I hoped this patch would solve it:

http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff_plain;h=0eedf4ac5b536c7922263adf1b1d991d2e2397b9;hp=acdd80d514a08800380c9f92b1bf4d4c9e818125

But according to Steve Kieu, the problem is still there in 2.6.13. It's 
slightly odd as Steve was previously a sk98lin user and initially reported 
this problem for sk98lin in 2.6.13 whereas it did not happen with sk98lin in 
2.6.12.

Any ideas?

Thanks.
