You're right Leshcat, it is very difficult to improve original driver...
My own driver was just a test afterall, and i think i will only keep the
video mod. Talking about this one, it was made originally not by me, but
by a russian guy called "DK".
I personally dont think it is possible to improve only by soft the night
ISO sensitivity. It must be hardware fault !
Well, i guess it is still possible to play with driver parameters.
Actually i'm trying to mod the zoom part, and instead of original shaky zoom
steps x1, x1.1, x1.2,..., x3.9,x4, it should be possible to get a FLUID
zoom in only two steps, from x1 to x2 and from x2 to x4.
For those interested in modding, here is the part :

seq_set_prop_6 =
#SET_REG(24,01) // ZM_SMTH_INTERVAL = 1
$s4 %0 // Place value in reg 4
$s5 40 // Place value 64 in reg 5
$*5 0a // Multiply reg 5 by a
$/5 r4 // Divide reg 5 with reg 4
$"Cam_mag_value_%5"
#COM_EVENT(61,$w5);

I tried the following, but unfortunately it doenst work :

seq_set_prop_6 =
#SET_REG(24,01) // ZM_SMTH_INTERVAL = 1
$s4 %0 // Place value in reg 4
$-4 09 // Sub 9 from reg 4
$s5 40 // Place value 64 in reg 5
$/5 r4 // Divide reg 5 with reg 4
$"Cam_mag_value_%5"
#COM_EVENT(61,$w5);

What i was waiting for :

value 10 (no action at zoom) :
64/(10-9) = 64 (64 is no zoom)

value 11 (1 click on zoom key) :
64/(11-9) = 32 (x2 zoom)

value 12 (next click, so 2 click on zoom key) :
64/(12-9) = 21 (nearly x4 zoom, real x4 zoom is 16)

you can do as chengrong did:

in his super camdriver, he set two zooms, the linear zoom and the normal zoom. i like the linear zoom(this is smoother than the normal one).

Well, he made those drivers for K750, w800 and w810. I just said this because i thought you could do it too with this driver. And yes, you can find this driver in this forum.

If we look to topic "Super camera driver for k810"
http://www.esato.com/board/viewtopic.php?topic=135737&start=6705

We can see, that they ve done a lot about driver(tested personally),
quality is really high,and slow motion in night is almost never seen. Ofcourse we can blame camera module in K550_W610. But i doubt that it cant do pretty almost the same results as k800/k810.

Not mentioning that K750 night "some of them" driver was awsome:no green dots in nightscenes and 20 FPS . Pretty empressive ,if to see k750 camera module.

So..in my opinion there is a lot of stuff what you can do about driver
