it seems to affect much more than that, please see below

SATA probing takes quite a bit of time, and with the asynchronous infrastructure other drivers that run after it can execute in parallel. Network drivers do tend to take some real time talking to the hardware, so running these later is a good thing (the sata probe then runs concurrent) This saves about 15% of my kernels boot time.

scsi, ide, macintosh and nubus will be now init-ed after network. No problem for ide but I'm not really sure about scsi...
