I recently had to move my cable modem to another room since it
couldn't maintain a signal on the old line in my bedroom. My G4 was
connected to the router via Ethernet so I had to find a way to get it
connected. Initially I was going to get an original AirPort card,
but quickly abandoned that idea once I found out they were selling
for $150+.
Anyway, I started doing some research and found a couple of reports
that said the Buffalo Technology WLI2-PCI-G54S worked. I found one
at the local Best Buy for $29. My research showed that most PCI
cards would work if they had a Broadcom chipset, but even then they
might not work if had the wrong version of the chip. (the only
802.11g Broadcom chip based card I had problems with personally
was the Microsoft MN-730 model (discountined long ago) which needed some plist editing mentoined
in older article here.-Mike)
Anyway, this one works fine. I made sure to download and install the
latest version of the AirPort software from Apple before installing
the card. After installing it and booting up, OS X didn't seem to
notice the card until I went to Network Preferences, upon which it
said that a new AirPort network port had been detected. After that I
just had to choose my wireless network from the AirPort icon in the
menu bar.
Here are the nerdy details:
Buffalo Turbo G Wireless Desktop PCI Adapter Turbo 125 High-Speed Mode
UPC: 47464 10908, Item number: WLI2-PCI-G54S
Here's the Best Buy link. You can check the inventory of your local
store and see if they have any.
Let me know if you need any additional information...

I've added this to the previous item on Airport 3.x compatible PCI/PCcards in the FAQ's networking section. (Some "Buffalo" 802.11g adapters in the past were listed as MacOS compatible on the packaging IIRC.)
