In looking at the docs, I realized that the mach64 seems not to support 
mipmapping on the secondary texture, as there is only one register for a 
secondary texture offset, as opposed to the 11 for the primary texture. It 
seems as the though the second "texture unit" isn't really a fully fledged 
texture pipeline as it is in other cards (Rage 128 has 2 separate tex_cntl 
regs and a full set of offsets for the second texture unit).

And lending credence to the assertion that mipmapping is broken in 
hardware on mach64, I compiled the mipmap Mesa demo in Windows and the ATI 
driver doesn't support mipmapping either, you just get a yellow triangle.
