man XFree86:

-bpp n No longer supported. Use -depth to set the color
depth, and use -fbbpp if you really need to force
a non-default framebuffer (hardware) pixel format.
-depth n
Sets the default color depth. Legal values are 8,
15, 16, and 24. Not all servers support all val
ues.
-fbbpp n
Sets the number of framebuffer bits per pixel.
You should only set this if you're sure it's nec
essary; normally the server can deduce the correct
value from -depth above. Useful if you want to
run a depth 24 configuration with a 24 bpp frame
buffer rather than the (possibly default) 32 bpp
framebuffer. Legal values are 8, 16, 24, 32. Not
all servers support all values.
