Graphics with intel 945G extremly slow

I've bought a Dell Optiplex FX160 with Intel Atom N230 and (this is the problem) a 82945G graphics controller.
2 GByte SSD Harddrive
1 GByte DDR2 Ram
I want to run Porteus in textmode only.
The graphics is so extremly slowly, that I'm not really able to scroll a ncurse based application in textmode. What can I do ?
Older thin clients like HP 5000 with 700 MHz CPU and 256 MByte Ram runs smoother than the Optiplex !

Perhaps its a modesetting issue,
Please post the output of following commands
lspci -knn
lsmod
You may redirect them to a file first to be able to upload.
If KMS enabled driver (like i915) is not used then you may try enabling standard VESA framebuffer with following cheatcode:
Thanks

Thanks for replying my "request",
I've maid a fault:
I have two peaces of Optiplex FX160 and I'm bewildered due to the fact, that one has an i945 graphics chip and the other has a SIS 671 chip. This I've found out by entering lspci -knn.
The one with the Intel Chip works fine. So the extremly slow one is this one with SIS on it.
I've made a search in the internet and now I know: The "problem" is, the chip is very slow and thats not the fault of Linux / Porteus !
So the problem is "solved", thanks a lot to fanthom

Even SIS GPU should be good enough for text mode.
Please enable VESA framebuffer with 'vga=792' parameter and check if that helps. If this resolution is not supported then you may try these:
