You make it sound much worse than it is. Apart for HPA, I'm not aware of
any setups that require extra treatment. And the amount of reported bugs
against it are pretty close to zero :-)

No, it's not.

*ahem*.

I needed to do this to cure IDE hangs on resume:

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.18-rc3/2.6.18-rc3-mm2/broken-out/ide-reprogram-disk-pio-timings-on-resume.patch

Are you watching the suspend mailing lists? There's no shortage of them:

suspend-devel:	http://dir.gmane.org/gmane.linux.kernel.suspend.devel
linux-pm:	http://dir.gmane.org/gmane.linux.power-management.general
suspend2-devel:	http://dir.gmane.org/gmane.linux.swsusp.devel
suspend2-users:	http://dir.gmane.org/gmane.linux.swsusp.general

I'm currently trying to help out one Sheer El-Showk, whose piix ide
requires 30 seconds of floundering followed by a bus reset to resume:

But I know next-to-nothing about ATA.

It's not surprising you're not getting many bug reports. It's common for
several things to go wrong during s2ram, and the user often ends up
looking at a hung system with a dead screen. It takes some quality time
with netconsole to even begin to narrow down that it's IDE hanging the
system, after which you can *begin* solving the no-video-on-resume
issue.

I agree.  Moreover, the disk-related resume-from-ram problems are the hardest
ones (the graphics may be handled from the user land to a reasonable extent).

Actually, I'm looking for someone who'd agree to be Cced on bug reports where
we suspect the problem may be related to IDE/PATA/SATA . ;-)
