video module limited after suspend

Hi,

I have ACPI compiled into the kernel and various subsystems as
modules. The 'video' module seems to have a problem, though -- it works
great on first boot, but doesn't work correctly after a suspend/resume
(I'm using suspend2, unloading and reloading the video module after
resuming).

The symptoms are that all subdirectories of /proc/acpi/video/VGA/
disappear -- which means I can no longer set the LCD brighness. All I
have is this:

total 0
-r--r--r-- 1 root root 0 Jun 17 18:25 DOS
-r--r--r-- 1 root root 0 Jun 17 18:25 POST
-r--r--r-- 1 root root 0 Jun 17 18:25 POST_info
-r--r--r-- 1 root root 0 Jun 17 18:25 ROM
-r--r--r-- 1 root root 0 Jun 17 18:25 info

Any hints?
