Well running 1009 still on mine and it works perfectly, which of course means I have no reason to consider upgrading the bios. Upgrading is for fixing problems. If you don't have any, don't upgrade, sice the only thing it can do is either nothing or break something. It can't be better than all working after all.
Yes, you are right, but this upgrade is for the support for the new ad core (Venice). So this means we are stuck with the running processor. Or maybe there will be an other fix later ...

Does ubuntu use vesa or something instead of the binary only driver (which does agp drm stuff)?
Ubuntu use xorg instead of xfree, the driver is "ati" (BTW, "ati" doesnt work on my system both with 64 and 32 bit, I've to use "radeon").
What I did. But this is not a long term solution. And the politic of Asus is not acceptable. 1009 is not bug free. i.e. : try the auto overclocking mode..

The monitor will not crash the machine. :) Well unless the DDC parser is garbage and the data is bad. If you have no problems with 1009, just keep using it.
Some years ago I had a bios upgrade (I used to think you should always upgrade too) which made the adaptec 2940uw card just disappear (never initialized) which of course made booting from the scsi hd a bit of a problem. Fortunately I kept the old bios on a floppy so I could boot the system from floppy (after disabling the scsi bios in the adaptec setup since it actuall crashed the boot when enabled), after which I could downgrade the bios, then reanable the scsi bios and the system was back to normal. Now I only upgrade the bios when I have stuff not working that is listed as fixed.
The changelog for the ASUS BIOS doesnt represent the changes. Many other things have been changed : the way the DDR is managed, some options have beed added, other suppressed...
dvdwriter firmware on the other hand I do find uses in upgrading since they keep adding support for newer media (and sometimes they up the speed of the drive too like on the PX716A which went from 4x to 6x DL support). I guess you can send back a message to asus that the 1011 bios breaks nvidia and ati accelerated X drivers while 1009 works. Maybe they can consider what they may have broken. Who knows what else it might affect in suttle ways.
This is what I did and if you refer to my previous post they reply tehy have no UNIX/linux support.
And I consider *this* is the worse in ths problem..
