FYI, I've switched my primary desktop to AMD64.

I finally worked up the nerve to commit to eating my own dogfood.  :-)

I've actually been doing my primary development on amd64 boxes for a while,
and now that the consumer products have been officially launched, I figured
it was about time.  Most of the key components are in place.

I've upgraded my home machine to an Asus SK8N + Athlon64 FX-51 (niiice!).
My i386 box is in pieces, there is no going back now.  For some strange
reason I've had to pay attention to some of the sharp edges I'd been putting
off for a while.

I'm using an older nvidia geforce4 ti4200 for the video, so I had to fix
a misconfiguration in the Xserver (I forgot to have it open /dev/io).  The
previous cards I'd used were all matrox which were solely mmio driven and
didn't run into this problem.

I've been working on getting mozilla-firebird up and running but that is
easier said than done because the core infrastructure (nspr, xpcom etc)
haven't got official support for amd64 yet.  There are patches in the
bugzilla database though.  If all else fails, I'll use remote X from my
laptop or something evil like that.  Or finish off the 32 bit i386 binary
support (I need to do that anyway - I haven't even tried to see if a
FreeBSD/i386 binary of mozilla works, it might already work)

Anyway, the 24 hours later status is: Thumbs up!

And now to do the same thing to my work desktop.  I'm planning to use
an Asus K8V + Athlon64 3200+ there.

Anyway, in case anybody is interested, the dmesg of my home box looks like
this:

Those disks are serial-ata maxtor drives on the serial-ata ports of the
controller - the ATA code doesn't know how to recognize that and is calling
them UDMA133.

I've got all those sio ports in there because I no longer have an ISA slot
for my Specialix XIO multiport controller to go in. :-(  (Say, does anybody
have a PCI SI/XIO host adapter laying around?)

Cheers,
-Peter
