Just successfully gone to 13.37 on a 64 & 32 bit box, and my question concerns the 64 bit. Beyond 13.37 it has later versions of pixman, libdrm, and Mesa (with llvm support which slack normally doesn't) along with llvm-2.9. I have been advised to do this because of my unusually crap ati GPU doesn't do vertex shading or summat.

I use wine (not video intensive stuff). Will I get away with 32 bit multilib versions that are different? Here's a list of the stuff in question.

mesa-7.9.2 (w/o llvm support) NOW 7.10.1 with llvm support
libdrm 2.4.23 NOW 2.4.25
pixman 0.20.6(?) NOW 0.21.8
xf86-video-ati - no change
xorg-server - no change.
llvm-2.9 compiled 64bit from source.

llvm is some on the fly compiler http://www.llvm.org
I'd welcome your thoughts. Ultimately it will blow up in my face, but I'm used to that :-/.

Things won't blow up.

The versions of 64bit and their 32-bit "compat32" counterparts do not have to match. Consider the 32-bit library layer as a separate independent entity. Those 32-bit libraries do have to be compatible with the C libraries (glibc) that were installed with Slackware - meaning that some old 32-bit libraries may have issues.

That's lovely, thanks. So I can just slap in the latest compat32.
