A lot of Rockshox forks can be internally adjusted from 100 to 80mm, the travel adjust versions IIRC (best check before purchase!)
Or, a RockShox U-Turn fork wound down to 80mm would do the same job
However the 2010 RS range only seems to have V mounts on the some of the Tora range, which are the opposite end to Sid's, still good forks, but not high end stuff.
Fox don't use `V' mounts for 2010
Magura have the low end Menja with 85mm & 'V' mounts available for 2010, never used Magura so dunno if they're any good or not
Marzocchi's 2010 offerings are also very low end forks with V mounts
I have some '08 Reba's with V mounts that were 105mm, add a spacer & they're now 85mm.
You may have to look for some older forks to get a good high end 80mm fork with V mounts
