Hi,
I do not know the right settings for 640 480 on the glamo. But
inverting will not work. You should try the output of gtf or cvt:

$ gtf 480 640 60
Modeline "480x640_60.00"  24.82  480 504 552 624  640 641 644 663  -HSync +Vsync

$ cvt 480 640 60
Modeline "480x640_60.00"   24.25  480 504 544 608  640 643 653 665 -hsync +vsync

$ gtf 640 480 60
Modeline "640x480_60.00"  23.86  640 656 720 800  480 481 484 497  -HSync +Vsync

$ cvt 640 480 60
Modeline "640x480_60.00"   23.75  640 664 720 800  480 483 487 500 -hsync +vsync
