Hi,
so we have actually 3 bugs here.

automatic selection of driver works only for pci and sbus, so some code
would have to be added to the server to make that work here.

By default, the newport driver requests 24bit depth from the server.
Later, it probes the hardware and, if it only discovers 8 bitplanes, it
gives up. The easy fix is something like:
diff --git a/src/newport_driver.c b/src/newport_driver.c
index 6bd7c9f..f82bee1 100644
--- a/src/newport_driver.c
+++ b/src/newport_driver.c
@@ -280,10 +280,10 @@ NewportPreInit(ScrnInfoPtr pScrn, int flags)
pScrn->monitor = pScrn->confScreen->monitor;
#ifdef NEWPORT_USE32BPP
- if (!xf86SetDepthBpp(pScrn, 24, 32, 32, Support32bppFb))
+ if (!xf86SetDepthBpp(pScrn, 8, 0, 0, Support32bppFb))
return FALSE;
#else
- if (!xf86SetDepthBpp(pScrn, 24, 0, 0,
+ if (!xf86SetDepthBpp(pScrn, 8, 0, 0,
Support24bppFb | SupportConvert32to24 |
PreferConvert32to24 ))
return FALSE;
and requires explicit configuration to use 24bit depth on hw that
supports it. The better way would be to try to reorder hw probing and
xf86SetDepthBpp in NewportPreInit.

And this is the third bug, not sure how to fix that one… Maybe there's
a way for the driver to inject the mode it wants to use into the
server's mode pool?
