Link /lib/modules/2.6.12-1-686-smp/build does not exist (or is not a link)

[Mathieu Malaterre <mmalater at nycap dot rr dot com>]

Hello there,

	I have just updated my debian system today, and it made the switch to
xorg. Unfortunately I am not able to compile fglrx anymore due to
missing kernel-headers for 2.6.12. I am doing:

4.1 Build with the supplied make.sh script
http://xoomer.virgilio.it/flavio.stanchina/debian/fglrx-installer.html#install

But the script is telling me:

Link /lib/modules/2.6.12-1-686-smp/build does not exist (or is not a link)

Anyone to confirm kernel-headers for 2.6.12 are not available ?
Suggestion anyone to get fglrx to compile ?

Thanks,
Mathieu
Ps: It's funny when I made the switch (without even recompiling) my dvi
dell screen was displaying: "Cannot display this video mode"
