Hi
Marcus has asking me to post the patches which are needed to get a
'stable' kernel using pcmcia. These patches disable some code which
trigger some fatal bugs and therefor they are just quick and dirty
hack. They don't solve the problem.
I have uploaded a new version of the pcmcia patch. Now the other
widely spread pcmcia brigde (tcic) is activated.
The pcmcia code depends somehow on cardbus functionality. That means
that even though there is no cardbus enabled it uses some parts of the
cardbus code. The only way out I see is to fix this, is to support
cardbus. But I said earlier for this I need a cardbus card :)
