package fglrx 2:8.723.1-0ubuntu4 failed to install/upgrade: fglrx kernel module failed to build

Built new computer with MSI 790X-G45 mobo , ATI HD 5570 video card , Acer X233H monitor. I installed Ubuntu 9.10, upgraded to 10.04, then went to System->Administration->Hardware Drivers. Clicked "Activate" to get the ATI drivers. Got the crash symbol in my panel shortly afterward.

1) Description: Ubuntu 10.04.1 LTS
Release: 10.04

2) neil@sonata:~$ apt-cache policy fglrx
fglrx:
  Installed: 2:8.723.1-0ubuntu4

     2:8.723.1-0ubuntu3 0

3) I expected the ATI drivers to install, reboot, and have a sharper display.

4.) Instead I got an error about "driver could not install" and a crash icon in the panel, which took me here.
