On second thought, the usage of VESA for installation and then switching to KMS might have caused the mixed behaviour, i.e. that the kernel recognized and initialized both chips but X used only the integrated one. But I don't want to reinstall the system to test this theory.
I doubt it would make any difference.
Now, with the "Switchable" state, RADEON(0) lines (for ARUBA) and RADEON(G0) lines (for HAINAN) are present.

I would like to have PRIME functional so I will need to set "Switchable Graphics" in the BIOS. What xorg.conf magic should I add to make it use the ARUBA chip for display but still keep HAINAN active for PRIME?
According to the screen enumeration above, that's already the case.
I see.
https://bugs.freedesktop.org/show_bug.cgi?id=69694 may be helpful for troubleshooting the crash.
I looked at it and the symptoms from comment 17 and comment 19 (blank screen with only the cursor visible) looks like it's very similar to my case. Only when removing the "quiet" kernel command line option, more is left visible on the screen, not just the cursor.
Can Mesa/Xorg use both r600g and radeonsi at the same time?
Yes, that seems to work fine for others. You may need Mesa 10.1 or newer though.
Do you mean mean with Mesa 9.2.5 and Xorg server 1.14.4 in Fedora 20 at this time, it's not possible unless I compile my own llvm-3.5 SVN, Mesa 10.1 or 10.2 GIT and Xorg 1.15 GIT?
I tried to upgrade to rawhide at least in part:
[zozo@localhost ~]$ rpm -q kernel mesa-libGL xorg-x11-server-Xorg llvm-libs kernel-3.13.3-201.fc20.x86_64 mesa-libGL-10.1-0.rc1.20140208.fc21.x86_64 mesa-libGL-10.1-0.rc1.20140208.fc21.i686 xorg-x11-server-Xorg-1.15.0-3.fc21.x86_64 llvm-libs-3.4-4.fc21.x86_64 llvm-libs-3.4-4.fc21.i686
I still get the same problem. Attached is the log from both 1.14.4 (FC20) and 1.15.0 (rawhide), with this change so the timing info is cut off from the beginning of each line to make it easier to produce a diff between the two files:
[zozo@localhost ~]$ cat Xorg.0.log.hainan-active | cut -d ']' -f 2-
Xorg.0.log.hainan-active-no-timing
[zozo@localhost ~]$ cat /var/log/Xorg.0.log | cut -d ']' -f 2-
Xorg.0.log.hainan-active-no-timing-1.15
