How does "accellerated wscons" work? I thought wscons just presents
a dumb frame buffer device to the X server? Or can XFree86 figure out
"hey, behind this wscons, it's hiding an Mach64 chip, so let's use the
XFree86 hardware driver"?
I definitely lack some understanding how the pieces link together for
"X on wscons and hardware accelleration".

Yep, same here (U10, FFB). But that's really a minor thing.

I use wscons on U10/Creator3D with good success. -current kernel,
kernel compiled with
ffb* at mainbus0
wsdisplay0 at ffb?
# keyboard / mouse
wskbd* at kbd? # console ?
wsmouse* at ms?
options RASTERCONSOLE # fast rasterop console
options FONT_GALLANT12x22 # the console font
options WSEMUL_SUN # sun terminal emulation
options WSEMUL_VT100 # VT100 / VT220 emulation
and it works well. As far as I understand, it's non-accellerated, though,
as the XFree86 ffb driver is not used, only the "wscons" driver.

Is there a way to get "kernel oops" messages to the serial console,
even if keyboard+monitor are connected to the system? I have a PC with
a spare serial port available, and it would be useful to actually see
what happened, instead of just seeing "hmmm, frozen. bad. power-cycle
