Well, I do care, but if it's HP, it will have the same PCI vendor id, so 
it should be the same.  The change that Bjorn proposed won't actually 
change anything in the current kernel, it will just remove some dead 
code.  So I think everything is ok.  If the older HP systems won't work, 
we actually haven't changed anything, but I'll take a patch to fix them.
