I tried both logical and physical modes when writing the VM ext and found
that physical mode was much more stable on my TT. I really think that you
should add a define so one can set which mode to use when compiling.

Could you track down where the buserror occurs?

Ehhh *flush* I actually forgot that... When I don't do something at once this
can happen... You can get the current version I have on my HD at once since
I don't have that much time to work on it. Nag me if you don't get it tomorrow...
