1. remove all x modules you don't need want or use (so just keep your driver
that you ened for that video chipset and only the input drivers you need and
extensions you need). actually reduce the extension modules you use too (eg no
glx if you don't need it etc.)
2. reduce font installations of x core fonts to minimum (fixed + cursor) so the
mount of font index files to parse and their size is tiny
--- now onto advanced stuff
3. put all the libs x and x clients need in a ramdisk and load it as an initrd
no boot (ldd for x itself, then its modules, ldd on icewm, icewm and its data
files). (optional if you want to expend the ram - but hellishly fast).
4. start hacking your x drivers - remove unneeded paranoid chip reset cycles
(have done so before for an i830 chip since x reset the chipset so the
backlight went off and came back on which added about .5 seconds to startup
etc.).
