Alas ! I was not fully awake and I did not see ACPI was not enabled when I 
tested >-(

tested combinations :
no ACPI :
X11 with neomagic driver : OK
X11 with vesa driver : OK (but no XVideo)
no external disk drive detection on the firewire

with ACPI :
X11 with neomagic : instant freeze of the machine
X11 with vesa : OK
correct external disk detection and use

in all cases dri is disabled, and no drm modules are loaded :

this is with FreeBSD 5.2-CURRENT #3: Sun Feb 29 02:09:56 CET 2004 and 
XFree86-Server-4.3.99.15_2 (locally compiled).

I suspect I'll boot and reboot until I change the machine (as soon as a 
notebook K8 arrives ?)

I did not see any options related to an IRQ for the VGA display in the BIOS 
setup (but setting "PnP OS" to NO crashes the machine)

this a PCG-F707 VAIO from Sony, with a very limited BIOS, and for which I did 
not find any "ACPI patch" file (ASL).
