Are you sure about its Lenovo incompatibility?!?!
I had a 1490 sitting around here. I popped it in, and the BIOS started whining about an unrecognized network card installed and refused to boot. Sorry to give the bad news. :(I ended up ordering FRU 39T5578, Lenovo ThinkPad Wireless PCI-E AR5BXB6. Spent US$23 plus shipping, works great. I did a search on eBay for (39t5578,39t0499,40Y7026), which searches all three valid FRUs for the card.
Did you try the no1802.com file?It would be a great solution!
Unfortunately, seems that this can't be bypassed in newer models. Some of the [T/A/X]4x series and all of the 6x series override this fix.
Not sure I can be bothered with having external sound adapters - you think there will be a fix one day?
Taruga is working on a new version of the AppleHDA patcher, due out "any time now", which should help us out. Apparently, there are a lot of fixes for the AD198x series, including our AD1984. In the meantime, I , too, use a USB dongle for sound, as I only use headphones anyway.I can't wait for it to be native, though.
