Is there any way of issuing a PCI reset (safely) without rebooting? I am
developing a peripheral device (using a pci card with an FPGA and a plx9080
pci interface), and find that its local bus is prone to hanging up. It
would be nice if I could just reset the entire device via the PCI reset,
without having to go through the hassle of a reboot. Is this wishful
thinking?

Yes. Try to narrow the circunstances under which the device locks and avoid
them at all cost is the best to be done.

Why don't do a local RESET by writing in CNTRL register of the PLX9080 ?
(PLX datasheet page 79 bit 29 and 28 for reset and reload eeprom config)

Not generally.
Systems that support hot-plug PCI also have the ability to reset individual
PCI slots (ISTR that it's a requirement). Sadly, this facility is not
generally available on "normal" systems.
