Included is a patch for linux to add a PCI vendor/device ID for the
Radisys ENP-2611 board.  The ENP-2611 is a 64bit/66MHz PCI board which
hosts an Intel IXP2400 network processor, has three GigE interfaces,
runs linux and generally kicks ass.

Please review and apply the following patch if you find it agreeable.

This patch does not make any functional changes, but does improve
both performance and memory usage by rearranging structure elements.

The need for these changes became appearent during a code review of
the disassembly involving this structure. The memory footprint of this
structure is made smaller by grouping the byte fields next to each other.
The access of the list_head can be simplified by making it the first element
of the structure, thus avoiding a needless add-immediate without negatively
impacting any of the other accesses.

This patch fixes a null-pointer dereference when hot-plug operations

This patch adds some PCI Express register constants to <linux/pci.h>

For my device, setting the Max_Read_Request_Size value in the PCI
Express device control register makes a huge performance difference.
I wanted my driver code that does this to be a little more
self-documenting than:

	pci_read_config_word(mdev->pdev, cap + 8, &val);
	val = (val & ~(5 << 12)) | (5 << 12);

I went a little overboard and added all the basic device register
fields.  If desired I could go even further overboard and add the
link, slot and root registers as well.

This patch is based on Matthew Wilcox's patch for pciutils, corrected
for some PCI Express spec 1.0a changes.

So found this bug in the ISAPNP part of the code, throughout the code it
use it's own data structure to reference it's base IO address, in the
ISAPNP code this was not being populated with any value hence it can't talk
to the card and so the driver fails.

As we've discussed in another thread, below is a diff that will do a set_par()
as late as possible when there is KD_TEXT<->KD_GRAPHICS switch.  The set_par()
will be forced in fbcon_resize() instead.

Not sure if this has repercussions with the other drivers, but this patch
fixed the X nv driver hanging when switching to the console.  (I believe the
crash is actually caused by an early set_par() -- while in fbcon_blank. 
Removing the set_par in fbcon_blank fixed the hang but caused cursor sprite
