Are you really sure about that? I got the includes in
/lib/modules/2.6.10-1.770_FC3smp/build/include/asm

[iocc at flashdance asm]$ ll */mach_mpspec.h
-rw-r--r--  3 root 145 Dec 24 22:35 mach-bigsmp/mach_mpspec.h
-rw-r--r--  3 root 145 Dec 24 22:35 mach-default/mach_mpspec.h
-rw-r--r--  3 root 146 Dec 24 22:34 mach-es7000/mach_mpspec.h
-rw-r--r--  3 root 289 Dec 24 22:35 mach-generic/mach_mpspec.h
-rw-r--r--  3 root 145 Dec 24 22:35 mach-numaq/mach_mpspec.h

It just wont find them. As I said I tried to link them, with no luck.
If I miss includes, do you have any idea what the rpm packet that have 
them could be named? Or what its named it whatever distro you use?

It seems that Im not the only one with this problem. These persons got the
_exactly_ the same problem with SMP and mga_vid:
http://article.gmane.org/gmane.comp.video.mplayer.user.matrox/174
http://article.gmane.org/gmane.comp.video.mplayer.user.matrox/212

Hmm.. If I edit mpspec.h and smp.h to point right to these files, #include 
<asm/mach-generic/mach_mpspec.h> and so on... I get no missing files errors 
but it wont compile anyway :/
