Hi Benny,

thanks for the tip.

I enabled all the options you suggested.

As I was, I disabled a lot of drivers and options I will  never use on 
the laptop (hardware not present, MCA bus and all possible devices, 
rarer used filesystem, etc).
The kernel is now 30% smaller! and Everything works.

Perhaps it works because of the enabled fixups or for less hardware 
probing, I suppose the former.

If I post a dmesg with the verbose options can the "fixups" seen in 
action and so we can finally understand the problem? Or should I just be 
happy that it appears to work :)
