There was a slight problem on upstream provided sources and as i knew
about it, i could not let the installation images go out in state where
one would have hanging X after firstboot (new installations) or hanging
X after boot. The xorg-x11-package is modified to disable DRI on Radeon
7000 (RV100) which is common on ia64-hardware as in the RX1600/RX2600
MC/ILO-board integrated VGA-conroller.

The other thing is that the shipped mx-package, if installed, will
render new yum unusable. The fedora-devel version mx-2.0.6 (the shipped
one is mx-2.0.5) doesn't have this problem and there is so little
changes that i just decided to ship with the new version. We really
wanted to get new yum on this release as it's using sqlite backend and
should work much faster after initial update.

This baby has been a long way. I did make it release now as there is no
reason to drag is as beta/rc for ever. It's not perfect, but it has
been working for me very very good. Specially the patched kernel has
been zero trouble free for what i've used it. Stable and working.

Now it's more like community thing to get things even better. There are
lot of mods from mainstream centos on this arch. Most of those are just
fixes to make things compile on alpha/axp tho. 

The xorg-x11/radeon/DRI is fixed here too, but more radical manner.
It's disabled for all radeon by default as i really don't render the X
unusable after installation, which was case in my tests on Radeon
9250/PCI. If it's resolved later, there will be update on xorg-x11 to
enable this.

So if you're a user, i am open for hearing about problems. Some of
those might be features and some fixable, but i am only one man with
lmited amount of hardware, so feedback is pretty much essential on
making this even better with centos-4.3 time frame.

DVD-image should be bootable even on IDE/DVD-drives now too. I made
ordering on the mkisofs, so the crucial parts are all located on
begining of the DVD. At least it now worked on my ES45 w/ generic
IDE/DVD-drive. Also the small boot.iso is there for network
installations.

The latest version of tog-pegasus didn't quite make it in this. It
doesn't weirdly sefault on late build process, but i didn't have time
to dig it really further yet. The tog-pegasus in the one that was in
BETA-set of sources. (i don't know if that even works tho :)

SPECIAL NOTE:

If you did install the 4.1beta for axp, you do have later kernel in
your system and the release kernel won't get 'updated'. One must make
manual actions to get the kernel installed if that is wanted. There is
something on these beta -> rel updates always.

There should be new centos-release dropped on 4.1beta updates.
That file, after updated, should direct all the beta-installations 
directly to release tree with pretty much automatically. If not, you 
should fetch it manually and install with rpm.
