7520/7530 chipset support in 4.x

[Tm4528 at aol.com]

Are there any efforts underway to support the new 7520/7530 intel chipsets in 
Freebsd 4.x? They seem to work ok with 5.x, but not with 4.x. Given that 5.x 
is still a ways off from matching the peformance of 4.x, those of us with 
production networking devices are unable to move up to the latest hardware while 
we wait for 5.4 or 5.5 or whatever. Its becoming a big problem.
