comcast wireless

I'm about to move to new location (rather unexpected), and will be tying
in to a Comcast supplied broadband connection (cable). The landlord has a
wireless network in place, using a Netgear CG814WG, which is a combo
modem/wireless/ethernet gateway (802.11b/g IIRC). Since it has rj-45
connections, it would be possible to run some cat5, though logistically it
would be a royal pain. I can't find much info on this device, it's branded
specifically for Comcast apparently, and of course Comcast seems to
suggest only Win and Mac are acceptable clients. For several years, I've
been on a ethernet LAN, gatewayed to a DSL connection, and wireless is a
bit daunting for me.

Unfortunately, I'm in a bit of a hurry, or I'd do the research myself, so
here's hoping some kind soul will take pity:

would a device like this work (Buffalo Technology AirStation 802.11b/g
Wireless Bridge Access Point)

also note, Micro Center seems to be leaning in favor of supporting Linux
(according to a /. article posted today), so would definitely be my vendor
of choice, plus they have a very nice store here in Atlanta. If I
understand correctly, this would allow me to connect my existing boxes,
all with NICs, rather than having to buy multiple pci wireless cards.

if I have to go with pci wireless cards, any specific recommendations?
Micro Center is first choice, also have Fry's, CompUSA, BestBuy, various
OfficeBorgs, assorted mom-n-pops; mail order isn't an option.
