Hello, list-members...

Regarding the issue expressed in the link contained in the subject
line: Me Too.

Here is the info on the card that worked until today, 
Saturday, October 6 2018:

vgapci0 at pci0:4:0:0: class=0x030000 card=0x304e1682 chip=0x68e01002 rev=0x00 hdr=0x00
vendor = 'Advanced Micro Devices, Inc. [AMD/ATI]'
device = 'Park [Mobility Radeon HD 5430/5450/5470]'
class  = display
subclass = VGA

Xorg is current from ports.

uname -a:
FreeBSD whisperer.chthonixia.net 
11.2-RELEASE-p4 FreeBSD 11.2-RELEASE-p4 #0 r339210:
Fri Oct  5 10:44:39 EDT 2018     root at whisperer.chthonixia.net:/usr/obj/usr  /src/sys/WHISPERER  amd64

(NB: regarding uname -a, since it may be of interest...I updated the ati driver from ports 
sometime prior to system update as indicated in uname -a; prior to the system update, the 
ati driver worked fine...for both the updated driver and the previous ati driver. 
In my experience, whatever this is, occurred after the world/kernel upgrade...to reiterate, 
it occurred on my machine *after* the update to the ati driver....which I think was 
Thursday, October 4....but perhaps sooner? Anyway, JIC it has relevance.)

What else....oh, yeah: none of the suggestions in the relevant thread have worked....none of the drm-*
possibilities enable startx to succeed; and the error I receive is this:

"drmn0: error: No GEM object associated to handle 0x000004B0, can't create framebuffer"

I take it the 0x0.... is associated with the particular card I use?

Further to if it's relevant, since my question below may be the easier route:

CPU: AMD A10-7700K Radeon R7, 10 Compute Cores 4C+6G (3393.72-MHz K8-class CPU)
Origin="AuthenticAMD"  Id=0x630f01  Family=0x15  Model=0x30  Stepping=1
Features=0x178bfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,MMX,FXSR,SSE,SSE2,HTT>

AMD Features2=0xfebbfff<LAHF,CMP,SVM,ExtAPIC,CR8,ABM,SSE4A,MAS,Prefetch,OSVW,IBS,XOP,SKINIT,WDT,LWP,FMA4,TCE,NodeId,TBM,Topology,PCXC,PNXC,<b25>,DBE,PTSC>
Structured Extended Features=0x9<FSGSBASE,BMI1>
XSAVE Features=0x1<XSAVEOPT>
SVM: NP,NRIP,VClean,AFlush,DAssist,NAsids=65536
TSC: P-state invariant, performance statistics

Perhaps it is time to try, again, to get this integrated GPU to work...however, my past efforts have failed,
always leading to a lack of a useful display....at least, with the current card, I can use a B&W console even
though I cannot use X.

So, advice is welcome: should I try to use the Kaveri Radeon R7 AGPU, or troubleshoot the PCI Radeon?

Thank you for any advice, and for the many hours of hard work put into 
the AMD graphics stackenstein :)

Best regards,
