I guess a single space is sufficient?

Better yet, I'd include sysfb.h unconditionally:
Unconditionally won't work as only x86 has this header. [...]
Well, in non-x86 code an #ifdef x86 looks ugly as well - but I guess 
better than not building.
[...] If there's a way to place a dummy into asm-generic which is 
picked if arch/xy/include/asm/ doesn't have the header, let me know. 
Not that I know of.
But if I include it unconditionally without any fallback, this will 
fail on non-x86. And adding the header to all archs seems overkill.
So why not drop the x86-ism and rename it to CONFIG_PLATFORM_SYSFB? 
Some platforms configure it, some don't. Then the prototypes could 
move into include/linux/sysfb.h or so and would be platform agnostic.

Thanks,
