1/ many reasons (perhaps your esktop is setto 16bit) colour check the internal formats demo on my site
2/ gluBuildMipmaps scales your textures to powers of 2 (prolly scales the largest to 256x256) do u have a voodoo1,2,3 by any chance

The voodoo 3 does not support a color mode higher than 16-bit. It also does not support textures larger than 256x256. So there is nothing you can do about it besides buying a different card.

Your games appear to look like 32bpp because the Voodoo3 dithers colours up to like 24bpp or so... I used to have a Voodoo3 long ago, and the same thing frustrated me. Buy an nVidia GeForce class card, and then you''ll be set to go. =)
