Having the user select udelay or none through the kernel config and then the kernel deciding "ah, you know what, I'll know better and use port access anyway" is _utterly_ broken behaviour. Software needs to listen to its master.When acting as an ordinary user, the .config is beyond my control (except on Gentoo). It is in control of the distro (Fedora, Ubuntu, ... but perhaps not Gentoo). I think the distro guys want a default behavior that is set in .config, with quirk overrides being done when needed. And of course the user in his/her boot params gets the final say.
Yes, and when the user/distributor specifically selected udelay or none as an I/O delay method it makes no sense whatsoever to have the kernel override that again -- the DMI hack only fixes something for the default case, when _no_ specific choice had been made (which the current setup can't express but mine did).
I feel particularly strongly (always) about that "listen to its master" bit. The kernel does not know better then whomever configured it, even when it does.
