Check your X server log file, and it will tell you why it
rejected 1152x864. A popular reason for Intel video hardware, is
because your BIOS CMOS settings limit the video memory to a small
amount like 1Mb or 2Mb. Increase the video memory amount in the
BIOS to 16Mb or more. Alternatively try using VideoRAM 16384 in
the config file Device section.
