Yes. Now I have to figure out why my motherboard is reported as KT266
when the manufacturer insists in all documentation that it is really a
KT266A based board ;-)


That is a bit odd!

VIA chipsets have interchangable Northbridges and Southbridges. The KT266 rather than KT266A might just be a typo in the kernel reporting: the significant difference is that you have the VT8233 and I have the VT8235, which has UDMA133 and USB2 support.

If I recall correctly, the difference between the KT266 and KT266A northbridges is in the memory bus caching architecture. tomshardware has an article on it.
