Recompile ubuntu vmhgfs for -generic instead of -virtual

Ubuntu jeos has not enough kernel, and for some reason, the version of the module struct between 2.6.24-5-generic and 2.6.24-5-virtual disagrees. First solution I managed to do was:

mkdir generic; cd !$
apt-get source linux-image-2.6.24-5-generic

cd -; mkdir virtual; cd !$
apt-get source linux-ubuntu-modules-2.6.24-5-virtual

cd virtual/linux-ubuntu-modules-2.6.24-2.6.24/ubuntu/vmhgfs

make TOPDIR=../../../../generic/linux-2.6.24/ SRCROOT=.

This should produce ../vmhgfs.o , which loads just fine into booted 2.6.24-5-generic.
