Am I understanding that the argument you're putting forward here is "cardbus started in year X, so from year X we can ignore 16-bit PCMCIA support" ? Given that PCMCIA support has been present in x86 hardware at least up to 2010, I don't see how that is any basis for making a decision about 16-bit PCMCIA support. Isn't the relevant factor here whether 16-bit PCMCIA cards are still in use on hardware that can run a modern distro? (And yes, x86 machines that have 16-bit PCMCIA can still run Debian Stable today.) -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last!
