GTA01 QVGA framebuffer has lines and bad colour

[usbhostman]

To reproduce, get a GTA01, ssh into it and run these commands:-
chvt 4 && echo qvga-normal > /sys/devices/platform/spi_s3c24xx_gpio.1/spi0.0/state && fbset qvga

The display will become black with some light lines on it and a line down the middle. If an image is displayed the colours will be wrong.
I have tried the fb.modes from stefan, but this did not make any difference. The fbset I am using says it is Version 2.1 (23/06/1999)

The fb.modes file says this:-

# Timings for GTA01 VGA and QVGA mode

mode "480x640"

# D: 26.000 MHz, H: 43.334 kHz, V: 65.657 Hz

endmode

mode "vga"

endmode

mode "240x320"

# D: 8.475 MHz, H: 24.635 kHz, V: 75.569 Hz

endmode

mode "qvga"

# D: 8.475 MHz, H: 24.635 kHz, V: 75.569 Hz
geometry 240 320 240 320 16
timings 118000 88 8 2 2 8 2
accel false

endmode

but if I change to qvga mode fbset says:-

mode "240x320-204"

# D: 25.000 MHz, H: 69.444 kHz, V: 204.248 Hz
geometry 240 320 240 320 16
timings 40000 104 8 2 16 8 2
rgba 5/11,6/5,5/0,0/0

endmode

while in vga mode it says:-

mode "480x640-63"

# D: 25.000 MHz, H: 41.667 kHz, V: 63.131 Hz
geometry 480 640 480 640 16
timings 40000 104 8 2 16 8 2
rgba 5/11,6/5,5/0,0/0

endmode

So it seems as if fbset is ill. I am using FSO milestone 2.

is this a hardware issue?
