I am having trouble booting from a real linux partition. I get the following output on the console before the boot process hangs: 
 
===========================================================================

I googled around and found that this error message is often associated with virtualization on AMD64 systems (which mine is). Here's an example:

So it sounds like the runaway modprobe has to do with the fact that my linux partition contains 64-bit binaries, while the colinux daemon (I'm using 0.6.3-pre-13) is 32 bit? Is it possible to compile colinux as a 64 bit binary and run it under my 32 bit Windows XP Pro SP2, and would this solve the problem?
