Why would you want a slower console for no gain?

Probably not, but the ati driver may not be detecting (something about) your
chip correctly; someone recently posted here how he could overcome a similar
problem by overriding the reference clock (IIRC).

BootX has nothing to do with X (in spite of its name ;), you can override the
amount of video RAM with the VideoRam directive in the XF86Config device
