Same again here. I've had no problem moving an LVM (on soft RAID too). 
To avoid the problem above all you need to do is ensure you rebuild your kernel
with all the options required for your new system, prior to moving it. 

I did this recently moving from an nforce based mobo, to an ATI based mobo and no
issues whatsoever.
