I noticed this too.  I've had a DLC on a generic 386/486 motherboard for
two months without problems, but the motherboard has a 486 bios, not a 
386 bios.

These chips are being sold a lot on 486 boards as they are significantly
cheaper than intel chips.  My guess would be that most DLC's are on 486 boards,
not as upgrades for 386 boards.  On the otherhand, cache off always gives
correct behavior, so it's reasonable for a default.

BTW...I just fudged and put a #define notyet_cyrix in locore.s (having source
is a plus ;-).  But something more standard like option FAST_DLC or 
DLC_CACHE_WORKS would be good.

One more bit unrelated?  Is there a reason PROCFS or PORTALFS aren't
in i386 conf/ALL ?
