sol 2.5.1 colormap allocation errors

[Angus Carr]

This problem shows you are using a 24 bit colour map.
Switch  the Xserver (openwindows) to an 8-bit mode and it will work in all
of the below cases.

X uses a colour map only in 256 colour map, and GRASS demands a colour
map. XDRIVER24 is a hack to use a 24bit display. It's a working hack,
however.
