I guess this confirms that it is X server doing the blanking.

You can look in the config file that is installed with the kernel

$ grep APM_DIS /boot/config-2.4.18-k7 
# CONFIG_APM_DISPLAY_BLANK is not set

but you seem to have ruled this out as being the issue in your case.

Yes and no. I *also* use /dev/gpmdata with a gpm configuration of

device=/dev/input/mice
responsiveness=
repeat_type=raw
type=imps2
append=""
sample_rate=

So I have two otherwise identical "InputDevice" sections in my
"ServerLayout" section in XF86Config-4. One is for /dev/gpmdata and
the other is for /dev/input/mice. I can't recall why I did this (it's
been nearly two years), but probably it was to allow me to start/stop
gpm independently of the X server.

I'm not sure if this relevant to your issue, but there it is anyway.

Cheers!
