Hi. Having made the swap from 32 to 64 bit hosts myself this month, I have found them to be very reliable and without the problems you seem to be happening.
You are using a really old kernel. I suggest upgrading both the host and guest kernels to something more modern. Previously I had been using 2.6.7, and this definitely caused problems in the move to 64 bits. 2.6.18 for me ran but had the odd little quirk which made it problematic. You dont say what version your guest kernel is, but try to get both updated. The other thing which caught me out was the uml tools, which I compiled on another machine. When I upgraded the readline library had undergone major revisions, and so the tools needed to be recompiled. Do "ldd" on the tools (like uml_mconsole) to make sure they all link to current dlls. You should really have /dev/shm as a tmpfs mount. Never seen a standard install without this as default (but I use fedora). I also originally had con2 to 7 in the inittab of the virtual machine. Why not give all the con2..7 devices a pty? But thats a longshot. Best of luck.
