snd_neomagic crashes on FreeBSD 5.4

[Lila]

Hello!
sorry for troubling you, I'm and absolute FreeBSD beginner and I need some
help with configuring devices.
Last week I tried to install FreeBSD on my laptop, a Omnibook 900, wich has
been consdered "FreeBSD Compatible" long time ago.
Everything was fine, at least I can access my FreeBSD login and even run
KDE, but it is far from being tuned.
I first notice each time I try to kldload snd_neomagic to have my sound card
working I have a prompt  saying:

pcm0: <NeoMagic 256AV> mem 0xfe700000-0xfe7fffff,0xfe00000-0xfe3fffff irq 10
at device 0.1 on pci1

and system frozes. The same happens if i try to statically compile
snd_nemagic into kernel.

I started checking all IRQ and settings: I know audio must use IRQ 5 for
multimedia devices, and IRQ 10 shared with cardbus and USB, for audio, I
tried to add lines on device.hints but having pcm0 on pci1 is useless.
vmstat -i says cbb0 and cbb1 are on irq 10, but says nothing about usb (wich
works properly) or pcm

I also noticed my serial port (sio0) is not probed.
Any suggestion? should I try anything to debug it better?
Thanks a lot
Lila

Here is my dmesg if anybody can found it of any use
