Thank _you_ Ben.

By following your good advice, I modified WITHOUT_MODULES and got it to 
look like this:

WITHOUT_MODULES= firewire bwi bce bfe iwi iwn zfs 3dfx 3dfx_linux 
amdtemp en em ep esp et ex fe fdc ae age ale de ed ida ie if_faith igb 
nge reiserfs rl s3 ti tl xfs

by doing so, I got rid of 70 modules and reduced kernel compile time 
considerably.

I will be playing around with it (most likely trying to get just sound 
and snd_hda instead of every snd_ module .. and just if_bge instead of 
all of the if_someethcard modules) and see what I get.

Should I get something interesting out of it, I will comment it in here.

Once again, thanks a lot for your interest, investigations, work, kind 
answers, and good advice on this issue. I really appreciate it, and it 
_did_ help :)

My Best Regards
