Bug#572311: No display output from Radeon RV610 on Alpha

[Michael Cree]

If I compile the ati/radeon video driver from fdo git master (commit 
4975658f05) with default CFLAGS (i.e. no byte-word extension), except 
for the module src/AtomBios/CD_Operations.c which I compile with the 
-mbwx compiler option, then I get a working video driver.

Looks like the problem is in src/AtomBios/CD_Operations.c.

Cheers
Michael.
