With both my laptops kernel-pcmcia-cs was not installed during an workstation install. This is very anoying since both don't have cdrom's so I need pcmcia to install pcmcia, chicken and egg problem. Solved by using the rescue disk but this is far from userfriendly. I know there was some discussion about not installing pcmcia for normal workstations that is fine by me, but not having it on laptops is a pain.
Did you select the 'laptop support' component?
I saw, and just installed beta4 and still see no such component when doing a laptop install, or does a laptop install require one to use custom, that would be not so nice.
ehm "laptop install" = "worktstation install", duh
This will be fixed in beta5.
