Default Some problems with virtualbox

Hi everyone, after I installed virtualbox, when I compile the kernel and execute "make modules_install", the message appears:

WARNING: /lib/modules/2.6.33-gentoo-r2/misc/vboxvideo.ko needs unknown symbol drm_open


WARNING: /lib/modules/2.6.33-gentoo-r2/misc/vboxvideo.ko needs unknown symbol drm_fasync

and when I execute "modprobe vboxvideo", it saied



FATAL: Error inserting vboxvideo (/lib/modules/2.6.33-gentoo-r2/misc/vboxvideo.ko): Unknown symbol in module, or unknown parameter (see dmesg)

the output of dmesg is :

vboxvideo: Unknown symbol drm_fasync
vboxvideo: Unknown symbol drm_poll
vboxvideo: Unknown symbol drm_core_get_reg_ofs
vboxvideo: Unknown symbol drm_ioctl

vboxvideo: Unknown symbol drm_init
vboxvideo: Unknown symbol drm_vblank_init
vboxvideo: Unknown symbol drm_mmap
vboxvideo: Unknown symbol drm_core_reclaim_buffers
vboxvideo: Unknown symbol drm_release




But when I use Virtualbox, all things are normal, I wanna know why there are so many warnings, and why I cannot modprobe vboxvideo

Does it because my kernel didn't include DRM?

Many thanks

I don't know anything about virtualbox but are you sure you have the
symlink pointing to the running kernel? I mention because it sounds
like something I would do. ;-)

I checked the symlink, and it is pointed to the running kernel~~~

when I recompile the kernel with DRM support, all things back to normal......
