I read your other posts (Corrected) on this issue. I too have the dreaded ATI
X200 Mobility version. This issue may not be ATI at all. There is a known
bug that has existed for the past two buntu version concerning not being able
to switch to a usable console (ALT+F#). There is also a fix posted for this
bug. The bug exists in NVidia video cards as well.
The synopsis on the launchpad appears to be that buntu intentionally broke a
working part of the OS to sort out an issue with power mgt. I am skeptical
of this, as I can not conceive of any sane developer doing this type of fix.
Here is the bug# and subject line:
[Bug 129910] Re: Blank ttys when using vesafb (vga=xxx)
The following is a slightly modified sample of one of the most recent posts
for correcting this problem. I fixed my issue by following the same basic
steps. Hope this helps.

I changed around the display settings in /etc/usplash.conf to be:
Then installed the proprietary fglrx drivers (in the process of this I had
need of a terminal when X would not start, only to find that those would not
work either! Only booting recovery console would *get a working terminal
Fixed it with the following steps:
sudo apt-get install hwinfo
sudo hwinfo --framebuffer
looked through supported vga modes and found one I liked:
Mode 0x0323: 1024x768 (+4096), 32 bits
sudo vim /boot/grub/menu.lst
found my kernel line and added vga=0x0323
sudo vim /etc/initramfs-tools/modules
sudo vim /etc/modprobe.d/blacklist-framebuffer
un-blacklist the module by commenting out line:
update the initramfs:
sudo update-initramfs -u -k all -v
Fixed with acceptable resolution and working usplash
