What I mean specifically is that the kernel dated October 7 works fine, and 
any more recent kernel hangs solidly if I boot it.  Obviously, this is 
somewhat inconvenient. :-)

The device in question is a PCI-X Neterion 10gbps card.  The output from the 
kernel when the device driver is loaded is:

Copyright(c) 2002-2005 Neterion Inc.
xge0: <Neterion XframeII 10GbE Adapter, Revision 2, Driver v2.0.0.6765> mem 
0xd8300000-0xd8307fff,0xd8400000-0xd84fffff,0xd8308000-0xd83087ff irq 25 at 
device 1.0 on pci129
xge0: Device is on 64 bit PCIX(M1) 133MHz bus

If there's more information I can provide I'm happy to do so, just let me know 
what's needed.

Is there a way I can disable vpd support at boot-time in some form -- i.e., 
via a tunable?  It would be very useful if these machines worked.
