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?
