The sytem I am trying to get the unmodified_drivers to work on is actually a custom linux distribution based on the 2.4.34 linux kernel with several other patches applied to it.  I have already investigated trying to apply the xen patches to the kernel itself, and the patches conflict with the grsecurity and/or openswan patches.  So, in the meantime I have been running the machine as a pure HVM, but I am looking for ways to increase it's performance.

If there is anything that I can do to help with this project, just let me know, and I will help out to the best of my ability.

Re-send, now that the list is back up.
These patches were originally developed for RHEL3-U8... I'm not sure 
what the differences are for CentOS5. I'm sure it would take a bit of 
development to get them working.

The guys over at RedHat had said they were planning on releasing a 
pv-on-hvm driver kit for older RHEL versions...but I'm not sure what the 
status is on these.

However - you are not the first person to inquire about these patches - 
indicating that there is a real desire to support 2.4 kernels.

Keir - you had originally rejected these patches for various reasons.
Have any other solutions been proposed that you find more acceptable?
