OK .. it obviously does rebuild, not sure why it is not building for you.

However, you don't need to rebuild this yourself as we are building a
kernel-vm that has this as its only change (change the clock from 1000Hz
to 100Hz):


When will these RPMS be available in the (plus?) repo?

Tip for the ESX users:
When using a kernel with a modified name, the VMware-config-tools.pl script 
"thinks" there is no fitting binary module present, and want to compile a 
module for the running kernel. But after compilation the script runs dead, 
because the pcnet32.ko module won't unload.... The script then waits 
When running the VMware-config-tools.pl with the -t option, it tries every 
module, and will come to the conclusion that the binary available module 
fits nicely... At that point there are also no unload problems...
