If you don't want FB, but you do want KBD, then you're stuck with FB
anyway, even though it isn't necessary. Perhaps I'm the only one who
ever considering building a config without FB?

I added them the last time you reminded me. See the following
message-ids for the thread where this patch was discussed and then
led to the V2 here.

I've re-added them to this thread, since the multiple
posting/reposting must have lost them again.

Testing-wise you don't really need to do much more then
'make oldconfig'. FB doesn't work on pv-on-hvm, the mod wouldn't
even init if you tried as there's a
if (!xen_pv_domain())
return -ENODEV;
I have tested a pv-on-hvm guest after this patch with FB off though,
which worked. For PV guests using FB, they'll work the same, as you
wouldn't want to change your config.
