Coldplugging the pcibus (/etc/hostplug/pci.rc) takes 2 minutes and 3.8
seconds using ash and 5.84 seconds using dash. I can tell you that you
notice the difference without measure anything.

the version is dash-0.5.2.7

I checked it out and the critical code is in /etc/hotplug/pci.agent in
function pci_map_modules There is the modules.pcimap (2211 lines here)
parsed for every pci device.

Scripts are here:

The patch did no noticeable difference.

I had to merge it manually. I have attatched a new patch against current
svn (revision 15335).
