Getting lastest aic7xxx drivers

[Chris Samaritoni]

Hi,

To make a long story short, I need to get the lastest aic7xxx drivers for 
4.8 Release. I know I could use cvsup to upgrade the system to 4.8 Stable, 
but due to too many changes that would occur, I can't do this. So how do I 
just use the cvs or is there some other way to grab all of lastest RELENG_4 
files in src/sys/dev/aic7xxx/


Thanks,
Chris
