[CentOS] Custom kernel needed for ndiswrapper? (for Linksys WPC54G wireless pcmcia)

Greetings:

I'm just installed Centos-4 on an IBM T-21 laptop.  So far so good.  Now 
I'd like to pop in a wireless lan adapter.  I'm looking at a buying a 
Linksys WPC54G adapter (although I haven't done so yet).

After doing some searching, it looks like the best way to get this card 
working is via ndiswrapper [http://ndiswrapper.sourceforge.net] and then 
to use Windoze drivers.

So I downloaded ndiswrapper and during the install, I received a warning 
message referring to "4K Stacks" and that NOT disabling 4k stacks can 
cause some drivers to crash. The docs went on to suggest I recompile the 
kernel to disable CONFIG_4KSTACKS.

Question: For really like to stick to the stock CentOS-4 kernel and not 
create/use a custom one. Has anyone had a problem using the Linksys 
WPC54G Cardbus adapter + Centos-4 and NOT had to use a custom kernel?

For that matter, since I haven't purchased the card yet, can I get a 
recommendation or two about a workable wlan cardbus (g) adapter that 
could most likely be found at Best Buy/CompUSA/Fry's ?  I'd like to be 
able to easily return the card if things don't work...

I did some searching a decent card and it seems that a number of good 
wlan chipsets are discontinued or hard to find, so I'm slightly confused 
as to what to get.

Thank you.
