lspci for JVC MP-XV941

Hello!

I recently installed Debian unstable on a JVC MP-XV941 subnotebook which is
apparently based on the J3N platform by ASUS according to the kernel messages
(asus_laptop driver). The laptop has already the latest BIOS version (0203).

After rebooting the laptop after the installation, I got a kernel panic which
turned out to be related to the modesetting. The machine is based around the
Intel 855 graphics chipset which means it's using the i915 kernel module.

I have tried both kernel 3.16.7 from Debian unstable as well as kernel 3.18.6
which is the most current kernel we currently have in Debian, both kernel panic
unless I adding "nomodeset" to the kernel command line. Thus, I need to resort
to running X.Org using the VESA driver since I can't use the Intel driver.

I have the laptop sitting here on my desk running Debian unstable and can
install kernels compiled from git to test any patches, so I am open to helping
to debug this issue.

Please let me know if you need to know anything else.

Cheers,
Adrian
