The ABIT AV8 and my ASUS A8V both have the VIA8237 chip. Theproblem with the VIA8237 is the same as all the rest: the chips are not supported by the kernel in RAID mode. Thereare probably people someplace hacking around the kernel drivers and maybe they will get things working someday.
The chip doesn't even have a RAID mode. With these chips, the RAID function has to be provided by software.
In Windows the RAID function is provided by the BIOS + the Windows driver.In Linux the RAID function is provided by md or dmraid. And it is working today.

This is not about theory, this is about certain chips and how they work and they don't work good enough to use their RAID capability.

That benchmarks were done on Windows. Therefore the results are influenced by the quality of RAID implementation in the BIOSes and Windows drivers. You can't draw any conclusions about how they will perform with Linux's md or dmraid.
