Yikes. I kind of need some of the modules in the mdk kernel. That is what is stopping me from geting the vanila kernel. I could try and find and compile those modules myself, but I will get more headaches with it than solve probs (it would take too long to get it all together again). I have a pretty sensitive hardware/drivers configuration (nforce2 mobo + radeon 9700 pro to start with...). It took me quite a couple of months till all the patches/drivers were available, and it took me about 2 weeks of fiddling with it till I got the radeon 9700 pro to play nice (to install the driver so I would also have openGL). I am pretty reticent in going through all the pains again just to gain better response. Last time I tried the multimedia kernel, it crashed on my config directly at boot... I hoped I could backup my current kernel situation and try a patch... hmmm... Makes my hair raise when I think of the option to reinstall all.... :) I think I will wait to see if someone reports success with this patch on mdk kernel. Thx for your answer.
