This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development. This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4.
Log ends with:
[ 20.702] (II) VESA(0): virtual address = 0xb36ef000,
physical address = 0xb0000000, size = 67043328

The vesa driver is at the mercy of the video BIOS to set modes. If the video BIOS call to set a display mode fails, there's nothing the X server can do to continue. So this is either a bug in the video BIOS itself, or in the real mode emulator executing the video BIOS.
However, Ivybridge is supported by the native Intel graphics driver in RHEL 6.3, so this should not be an issue in current RHEL releases. Closing on that basis. If you have issues with this graphics configuration in 6.3 or newer, please file a new bug with the details.
