It depends on your definition of "a few k" :-)

It will run fine on an 8086 with 512 kBytes of RAM, but I its possible
to get by with as little as 200kByte of RAM.

I work with embedded Linux systems and the standard configuration for
the stuff I do is with a small embedded processor such as the Motorola
MPC860 or the Axis Etrax 100 (about as fast as an i486) and 8MByte of
RAM and 4MByte of flash. It's really no problem running in 2MByte of
RAM and 2MByte of flash but then the system really just does one thing
such as initializing a routing table and then routing data back and
forth. To be able to get OpenSSL running in there and so on I really
need 8MByte of RAM.

Well, I think Solaris is still supported on my SPARCclassic, but I
really really wouldn't like to try it with only 8MByte of RAM.
