No true. Check the VX800 datasheet, page 445 (in xpdf).

I can test it this evening, Differences between ICH7 and VIA
are described in source code:

/*
  VIA SPI is compatible with ICH7, but maxdata
    to transfer is 16 bytes.

DATA byte count on ICH7 is 8:13, on VIA 8:11

bit 12 is port select CS0 CS1
    bit 13 is FAST READ enable
    bit 7  is used with fast read and one shot controls CS de-assert?
*/

Thanks,
