Scyld module configuration

I've done some more checking into this problem.  I added the line you 
specified into the config.boot file and rebuilt the boot images for 
phase 2.  The failure occurs when the modules are loaded for phase 2 (no 
suprise).  It appears from the boot text that the modarg parameter is 
being sent to the pci-scan module instead of the 3c59x module, pci-scan 
fails to load because of the invalid argument, and therefore the 3c59x 
module fails to load because it depends on pci-scan.

Is there a way that I can look at the modules dependancies generated by 
beoboot after (during) boot image creation.

Thanks for your help.
