XFree86 and Upgrading

["Kevin Smith" <kevin@netsmith.ltd.uk>]

Hi All,

Does anyone have a lay instructions on upgrading to XFree86 4.2.0 from
the following:

XFree86 Version 4.1.0.1 / X Window System
(protocol Version 11, revision 0, vendor release 6510)
Release Date: 21 December 2001
        If the server is older than 6-12 months, or if your card is
        newer than the above date, look for a newer version before
        reporting problems.  (See http://www.XFree86.Org/FAQ)
Build Operating System: Linux 2.4.18-powerpc-smp ppc [ELF]
Module Loader present

Thanks,

Kevin
