What?  There's more kernel apps than just ndis network drivers that get 
ported.  ndiswrapper is busted (which is used for a lot of laptops)
without 4K stacks.  My laptop is a Compaq and there isn't a Linux driver 
for the wireless.  I also discovered Fedora Core 4 won't install
on a Compaq Presario with SATA (stacks crashes). 

What are you saying?   People with wireless and laptops who run Linux 
can't because ndiswrapper is busted without 8K stacks?

Should be a configurable option 4-16K -- set at RUN TIME on the COMMAND 
LINE of the BOOT LOADER.   Peopl can set
profile=? why not kernel default stack size.   That way Fedora, ES, AS, 
and Suse can run out of the box on laptops like Windows,
or is M$ going to keep owning the desktop?
