I tried booting an old version of -current on a 486DX2/66 that happened
to have 16MB. It didn't work fine, even after I removed a stray 3MB
debugging trace buffer. Where RELENG_4 came up with about 12MB "avail"
in the boot messages, -current had only 8MB, and -current is much
hoggier later on too. There ends up being only 2-4MB of memory available
for user threads, and the system swaps too much to be usable.
The 486 was also unusable since it had become too slow -- more than
twice as slow as it used to be even before it starts swapping, due to
a combination of factors including a large wastage for HZ = 1000.
So I would say that minimum requirements are an i586 with 24MB. My
K6/233 with 64MB is still quite usable.
