Bug#615601: unable to override hw-detect/modprobe_error with preseed or kernel commandline

[Thomas Mieslinger <thomas@mieslinger.de>]

Package: debian-installer
Version: 20110106+b1

If, for example "usb_storage.blacklist=yes", has been specified on the 
kernel commandline, I was unable to override the resulting 
hw-detect/modprobe_error error with preseed or a parameter passed on the 
kernel commandline.

I've deleted db_get hw-detect/modprobe_error from bin/hw-detect but 
thats not really a workaround.

How do I disable usb_storage AND install without manual intervention?

Thanks

Thomas
