i have just installed bootchart and tested the system.
result was: the main delay (about 15-20s) is taken after bootchart completes its job.
i mean system blinks the screen and do some other strange things before gdm, but after bootchart.
may be this can have some correlation with this bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/332772
