Yes, it does not helps, with 256 it makes mess on X start, and freezes
console, with 64 it allocates 64 Mb, mostly for textures:

Seems to be enabled successful (both mode 4 and fast-write):

(**) RADEON(0): Using AGP 4x mode
(**) RADEON(0): Enabling AGP Fast Write
(II) RADEON(0): Depth moves disabled by default

But can't see any difference with glxgears as fps metter.
it is gives about 470 fps with default window size on 
ATI M6 16Mb + PentiumM 1700MHz
