Thank you for your response, Dmitry!

The patch did get gvinum in the kernel but then next problem came: gvinum 
command will not work. Looks like the first thing it tried is to load the 
geom_vinum.ko module which of course fails. I didn't have much time to look 
into this. I could boot non-PAE kernel create the volumes and then boot the 
PAE kernel with gvinum compiled it. Worked like a charm. Rebooting for every 
FS change though somewhat defeats the purpose of the volume manager.

So I removed the gvinum from the kernel and compiled just the gvinum module, 
installed it and it worked. Now I wonder what can go wrong with this setup. 
There must be a reason kernel modules are disabled by default and I have no 
clue what is the risk of running gvinum as kernel module. I will be testing 
the install soon and I will let the list know if I run into problems. Any 
advice of course is very welcome and highly appreciated!

Thanks for your help!
