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.
