Does i830 driver multimonitor support?

Hi everyone.
I got Advantech industrial PC with intel graphics 855 chipset.
this pc has 1 VGA and 1 DVI output. I need use them both i separate monitors.
in documentation i read that multimonitor supports just radeon i matrox drivers. Is that true? Seems that i830 driver work with 1 monitor only?

QNX6 supports some ATI Radeon and Matrox Millenium dual-headed cards. For Matrox there is support for the Millenium G450 & G550. For Radeon people have successfully run dual-head configurations with Radeon 7500, Radeon 9700, Radeon 9800 cards; others may work, but it is hard to can say for sure.
