I don't think so; I'm not sure what the PCI spec has to say about it, but I have not had problems doing byte reads/writes for longer PCI configuration registers. Bit 9 of the sysctl register for the TI 1410 is "socket activity"; it is read only and is cleared after each read. The key change is setting bit 14 (enable upstream burst reads).
Regarding the register at 0xc9, I don't think that is defined in any TI bridge data sheet; it is in a "reserved" range.
