Turning off copy-back has a global performance hit, so it's a pretty nasty

Yep, you should really fix the driver.....

....... does it use insx/outsx &
friends from asm/io.h, or does it dereference pointers directly, forgetting
the eieio's?

Please don't use in/out macros on PowerPC....especially on 8xx their
underlying address arithmetic will likely break more things that it
fixes.
Use memory mapped I/O (readb/writeb, etc.) and ioremap().....
