Yes.  Here, for example, is the "Screen" section from my
XF86Config:

Section "Screen"
    Driver      "svga"
    # Use Device "Generic VGA" for Standard VGA 320x200x256
    #Device      "Generic VGA"
    Device      "Neomagic Corporation|NM2160 [MagicGraph 128XD]"
    Monitor     "LCD Panel 1024x768"
    Subsection "Display"
        Depth       8
        Modes       "1024x768" "1024x768a"
        ViewPort    0 0
    EndSubsection
    Subsection "Display"
        Depth       16
        Modes       "1024x768" "1024x768a"
        ViewPort    0 0
    EndSubsection
EndSection

(I have two 1024x768 modes so that I can use "xvidtune -next"
to reinitialize the video hardware on my ThinkPad 600 after a
suspend & resume.)

Yes.  I have two identical lines:

Modeline "1024x768"    65    1024 1032 1176 1344   768  771  777  806 -hsync
-vsync
Modeline "1024x768a"    65    1024 1032 1176 1344   768  771  777  806 -hsync
-vsync

but you could have two different ones.

(See http://panopticon.csustan.edu/thood/XF86Config for my
complete XF86config file.)
