Any recent binary distribution of CMUCL should run
on either Linux 2.4.x or 2.6.x. I'm currently running
CMUCL-19a(pre3) on Linux 2.4.21, and CMUCL-19c on all
of Linux 2.4.21, 2.6.7, 2.6.19, and 2.6.20.

CMUCL has only "green" threads (single-process coroutines),
but they're well-integrated with streams and the OS's "select()"
function [e.g., a "blocking" read automatically deschedules
the current thread until input data is ready and runs something
else in the mean time], and can be used for running multiple
simultaneous web requests quite handily. I run (or co-admin)
several web servers that use CMUCL as a persistent server
behind Apache (in a variant of "mod_lisp" style). It works
well (at least for the modest loads we serve).
