7520/7530 chipset support for 4.x

[Tm4528 at aol.com]

Are there any efforts underway to support the now prevalent 7520/7530 
intel chipsets in Freebsd 4.x? They seem to work ok with 5.x, but its 
been widely reported that 4.x has serious problems. Given that 5.x is 
still a ways off from matching the performance 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.
