Subject: Status of pci express in kernel

Hi,

I've read today that intel is going to launch it's first pci express
chipsets soon. So i was wondering if the support of this bus was already
a work in progress or if it wasn't yet started ?

Thanks

PCI Express is backwards compatible with standard PCI, so even fairly
old Linux kernels boot and work fine with PCI Express devices. 2.6
kernels also have support for accessing the new features of PCI
Express (ie extended PCI header fields).

It's already in the 2.6 kernel tree.
