I'm getting this problem on my Latitude X1 too.

$ sudo modprobe -r mmc_core sdhci

displays "FATAL: Module mmc_core is in use." due to module dependencies. But this works:

$ sudo modprobe -r sdhci mmc_core

Now the modules are unloaded. After that, resume from standby goes fast and doesn't take 20 seconds.

After

$ sudo modprobe sdhci

That's the /var/log/messages output:

This has been already reportet in the sdhci-devel list: http://list.drzeus.cx/pipermail/sdhci-devel/2006-May/000852.html -- That's the answer: http://list.drzeus.cx/pipermail/sdhci-devel/2006-May/000855.html

So Pierre Ossman suggests to upgrade to a newer sdhci version: "This is a bit old driver. Bug your distro to upgrade to something newer
or compile one of the 2.6.17-rc:s for yourself."

And what now?
