XFree86 has been tested with Linux version 2.0.32 and several 2.1xx kernels.
It is known not to compile with kernel sources newer then somewhere around
2.1.70, due to incompatibilities in the joystick driver. Except for the
joystick driver, it works just fine with all 2.1.x kernels tested (including
2.1.88). It should work with any version since 1.0 without change. The
binaries and libraries are based on the 5.3.12 Elf C libraries, and the
1.7.14 dynamic linker ld.so
. You will at least need the 5.2.x Elf
C libraries to successfully use the servers.
