It's worked flawlessly for years. I wonder why the >problems now. Hi! Well, on those old boards the IRQ 5 had to be designated via jumpers or BIOS entries to a specific port. I once did some routing of the IRQ 5 to ISA only (because my old soundblaster was there), and wondered why my system (had an old ASUS PCI/I SP3 in, the predecessor to the SP3G) won't boot. There I discovered with diag software that my vid card (Miro 8S) actually also took the IRQ5, and was hardwired to that.... Because its only PCI 1.3 spec, I assume, there are some issues in general... Basically, you have to configure it properly with the IRQ routing, also take in mind that most vid cards also want one.
