as far as I know, you have described all the known issues we have also 
experienced with DriverLoader 2.39 on 2.6.24-rc1. We have experimental 
patches for all these issues except for the do_softirq fatal problem, I 
can post them if anyone is interested in them.

More work will be required to make DriverLoader compatible with the 
future 2.6.24 kernel. I will post when a solution to the do_softirq 
problem will be available.
