I'm getting exception 13 when trying to use the latest qemu-kvm-0.12.3 on slackware 12.2 w/ stock 2.6.27.7 kernel:

Code:

Google says this has something to do with Intel hardware and the way it handles real mode. The suggested fix is to run it with -no-kvm, but that's not much of a fix really.. so in the mean time I reverted to using qemu-kvm-devel-88 which works well, but is pretty old.

Is there any chance of fixing this so it will work with newer qemu-kvm releases? Does it have anything to do with the version of kvm-intel.ko being used?

I think that's the problem...
have you tried upgrading the kernel to follow qemu-kvm?
0.12.x series works pretty well on 2.6.32...

Try kvm-kmod from SlackBuilds which compiles new KVM kernel modules (the old ones are left untouched). kvm-xx is like installing both qemu-kvm and kvm-kmod in a single package. The folks at KVM are not planning any more releases of the kvm-xx line.
