[PATCH] fix radeon, r128 host & BAR value confusion

On some platforms, the values in the resource structures are not equivalent to 
what's in the BARs, so you need to distinguish between them.  This patch 
fixes both of the drivers to use the BAR value where appropriate to 
enable/disable ROM space access and also prevents the destruction of the ROM 
BAR value as it may be needed if the card needs to be posted again.  Please 
Cc me on any replies as I'm not on linux-fbdev-devel.
