  Why not just build pae kernels like I do in Titanium for i686? Does it

 I'm fine with that if there's at least nvidia module available.

*not?

VIA C3 (IIRC C7 too) don't do PAE as well.

3 years is very old? Come on...
I have 2 laptops, both are non-PAE... Only the newest one with C2D on 
board is.


Only the Pentium M is problem. Sonoma with PAE was introduced in 
early 2005, but older versions were still on market. Dunno how long 
pre-Sonoma processors were produced (suppose ~1 year).
IMO it's much too early to abbandon support for that processors...

I'd rather virtualize such systems on x86_64 hosts, but thats just me :)

Yes, and get to maintain two systems instead of one ;)
