I have a patch which allows a memory hole in linux at: ftp://rvs.ctrl-c.liu.se/pub/wingel/memory-hole-2.0.29.diff
Give "hole=15M-16M" as a kernel parameter to specify a memory hole. The patch also contains some code which should be able to automatically detect a memory hole and the amount of memory on a Intel 430 FX chipset, it should be safe on other chipsets too, but I haven't tested it a lot.
