Cyrix/IBM 5x86/6x86 CPU configuration tool

 Allows one to modify the internal configuration registers in
 the 5x86 and 6x86 CPU. These include specifying non-cacheable
 memory areas (important for e.g. graphics cards), I/O delays,
 cache write policy (WB/WT), write-gathering, and also enable an
 automatic standby mode where a CPU "halt" instruction cuts down
 power by a factor of 70 (from 20 Watts to 0.3 Watts for the
 6x86 P133+) when the CPU is idle. Especially the CPU power
 reduction cuts down on most temperature-related problems on
 many motherboards.
