* Remove casts from atari out_le32() and friends.
* Move accel functions' declarations to atyfb.h.

Improve atyfb_atari_probe():
* Call correct_chipset() so that more par members, par->features in
particular, get initialized.
* If probe fails iounmap() the mapped regions and continue probing for more
adapters.
Only verified to cross-compile due to lack of hardware.

Thanks! This call was indeed missing for the Atari case.

Some register were only set in aty_init() which is not called on resume.
I added the aty_resume_chip() function to reset those registers on resume.
Susped-to-ram now works on a HP Omnibook 6000 with acpi_sleep=s3_bios.

Good work Ville,
have checked this patches on my RAGE MOBILITY
on top of 2.6.17.11(added with some fuzzies)
Signed-off-by: Alexander Kern <alex.kern@gmx.de>
for all 9 patches
Best Wishes
Mit freundlichen Grüßen
P.S. I would like to iron out the long standing issue on my laptop
I saw about for along time. I can shutdown but reboot. At least TFT goes
black, leds go off and than nothing. Have you any infos about special
register state for MOBILITY before reboot?

No. My OmniBook 500 does the same thing BTW. I can shutdown but reboot
just hangs the laptop. I'm guessing the BIOS doesn't like the state in
which atyfb leaves the card. The reason I'm thinking it's the BIOS is
that my OB6000, which has nearly the same hardware, reboots just fine.
I also tried all of the reboot= kernel options but none helped.
Maybe we just need to restore some of the original state before reboot.
But I don't know if that's even possible. Do drivers get any kind of
notification about reboot?

I used to have the same problem (shutdown works, reboot hangs with black
screen) on my Vaio Z600 (Z505 in US/JP), but recent 2.6 (I use a Debian kernel)
seems to have this fixed.
But I still decided to use vgacon instead of atyfb on this laptop, as X shows
some noise when launched from atyfb.

Was that with atyfb? My OB500 reboots fine without atyfb.

Yes, with atyfb. On 2.4 with atyfb, reboot hangs. On recent 2.6 with atyfb,
reboot works fine.
