[Discuss-gnuradio] IRQ Conflicts

Firstly, Congratulations to all those who were involved in making this USRP, especially Matt and Eric. I am beginning to harvest its functionalities and am enjoying it.
However, I have some conflicts with the Interrupts in my Redhat 4 kernel I recently added  USB 2.0 daughterboard to my existing USB 1.1.  The IRQ 10 seems to be sharing the ehci, eth0 and VIA. And I am trying to get a unique interrupt for my ehci_hcd (USB 2.0).
My BIOS wouldn't allow me to allocate interrupts individually. In bios, I tried the resources controlled by option to "auto" and "enabled" the reset config data. This spread my interrupt devices, but the ehci is still being shared :-( Any suggestions would be appreciated.
Here is what I get when i do a cat /proc/interrupts
Thanks in advance.
