Comment 2 for bug 369550

Thank you for your investigation and proposed solution. This sounds like a great improvement in boot time.

I'm looking into getting it fixed in Karmic and forwarded to Debian.

My results (please note that you should use "sudo" for the modprobe call):

$ echo 3 |sudo tee /proc/sys/vm/drop_caches
3
daniel@base { ~ }
$ time sudo modprobe -n -q vboxdrv

real 0m2.076s
user 0m0.008s
sys 0m0.004s
daniel@base { ~ }
$ echo 3 |sudo tee /proc/sys/vm/drop_caches
3
daniel@base { ~ }
$ time find /lib/modules/`uname -r` -name "vboxdrv\.*" 2>/dev/null|grep -q vboxdrv

real 0m9.875s

sys 0m0.072s
