>How-To-Repeat:
boot NetBSD-current kernel with Nouveau framebuffer enabled on this hardware (Dell Precision M70 laptop)
>Fix:
Only partial fix known. The following 2 patches to change the PCI BAR and print some debug messages allow the PRAMIN to be mapped and the VGA fonts to be saved but, as shown below, the console still doesn't attach.

The thought occurred to me before, so since you agree, I'll give it a
go.

The thought occurred to me before, so since you agree, I'll give it a

definitely worth a try -- EAGAIN means someone else has already mapped

I added a comparison of bpa == c0000000 to bus_space_map and it didn't
trigger until I set bar = 1 in nouveau_subdev_instmem_nv40.c:

Just one thing here -- I took your latest version and added the debugging
line back in to replay the bus_space_map parameters. Here's the result:
drm kern info: nouveau [ DEVICE][nouveau0] BOOT0 : 0x042c00a1
drm kern info: nouveau [ DEVICE][nouveau0] Chipset: NV42 (NV42)
drm kern info: nouveau [ DEVICE][nouveau0] Family : NV40
drm kern info: nouveau [ VBIOS][nouveau0] checking PRAMIN for image...
drm kern info: nouveau [ VBIOS][nouveau0] ... appears to be valid
drm kern info: nouveau [ VBIOS][nouveau0] using image from PRAMIN
drm kern info: nouveau [ VBIOS][nouveau0] BIT signature found
drm kern info: nouveau [ VBIOS][nouveau0] version 05.41.02.29.a3
drm kern info: nouveau [ PFB][nouveau0] RAM type: DDR1
drm kern info: nouveau [ PFB][nouveau0] RAM size: 256 MiB
drm kern info: nouveau [ PFB][nouveau0] ZCOMP: 189440 tags
drm kern error: nouveau E[ INSTMEM][nouveau0] bar = 2, iomemt=c1136740, iomemsz=0, start=0
drm kern error: nouveau E[ INSTMEM][nouveau0] unable to map PRAMIN BAR: 35
drm kern error: nouveau E[ DEVICE][nouveau0] failed to create 0x1000400c, -14
drm kern error: nouveau E[ DRM] failed to create 0x80000080, -14
nouveau0: unable to attach drm: 14
So, the size and start of 0 definitely seem wrong. I suppose I'll try
my experiment with bar = 1.
