[PATCH] quiet non-x86 option ROM warnings

From: Jesse Barnes
Date: Tue Feb 15 2005 - 18:58:46 EST


Both the r128 and radeon drivers complain if they don't find an x86 option ROM
on the device they're talking to. This would be fine, except that the
message is incorrect--not all option ROMs are required to be x86 based. This
small patch just removes the messages altogether, causing the drivers to
*silently* fall back to the non-x86 option ROM behavior (it works fine and
there's no cause for alarm).
