Yes. This is ASUS L5G notebook. Driver page with the one and only 
Wireless driver is here: 
http://www.asus.com/support/download/item.aspx?ModelName=L5G

I'm running NDIS for about 1.5 months. And this panic first happens only 
yesterday, so I thought this is not the driver bug. BTW, here it is:

ndis0: <ASUS 802.11g Network Adapter> mem 0xfeaf8000-0xfeaf9fff irq 17 
at device 2.0 on pci2
ndis0: NDIS API version: 5.0
ndis0: Ethernet address: 00:0e:a6:c2:00:e4
ndis0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps
ndis0: 11g rates: 6Mbps 9Mbps 12Mbps 18Mbps 36Mbps 48Mbps 54Mbps

Full dmesg is at http://mcsi.pp.ru/dmesg.boot
