udevstart surprisingly slow

Greetings,
I've recently upgraded udev from 063 to 082 and then 084.

With 063, startup of udev was near-instant; with both 082 and 084, it takes a significant ammount of time (~15s) to create the base devices using udevstart or udevsynthesize (this one is taken from Debian, which apparently in turn taken it from SuSE; the rest of codebase is vanilla).

This issue appears on kernel 2.6.15.1 with SquashFS 2.2r2, SWSUP2 2.2 and VesaFB-TNG 1.0-rc1-r3 patches.

The init script used simply mounts 10MiB tmpfs onto /dev, creates /dev/.udev/{db,queue} directories, then runs udevd --daemon and then udevsynthesize or udevstart (tried both, same result).

I'm quite out of ideas, I don't think downgrading udev is the best solution, so I wonder: what takes such a long time in udevstart? What can I alter at my end, or is this a known bug (or feature)?

Thanks in advance for reply
