-current, AMD64 and matrox G550 = early hang during boot

Hi,
having an AMD64 Asus A8V-Deluxe with Matrox G550 and upgrading
to latest -current leads to an hang (now with funny characters
on the screen) early after starting the kernel.
SC_PIXEL_MODE is not set.
I have configured the devices: vga, splash, sc and agp though.
A compressed dmesg with the last working kernel is attached.

Anyone else sees this?
Is this amd64 or matrox specific?

Bye/2
