Hallo Martin (&all);

following your workaroud i have attached a external monitor to the EeePC 1015 via HDMI, and it works - i was able to install NetBSD 10.1 on it. But...On booting 10.1 after completed installation appeared the problem again (and in very interresting way :-)

NetBSD 10.1 is  bootting readable, w/o text resolution swithing on 1015 LCD (kernel phase), to the point, of kernel testing of radeon and switching it to the new resolution,
Then there are 2 scenarios: with HDMI external monitor attached, or with ONLY internal EeePC 1015 LCD 1024/600;

With external HDMI attached:
after switching radeon in kernel phase on external monitor is console set to text 120x33, simultaneously LCD on EeePc 1015 is with 64x18 (and upper half row19) showing a left upper subset of the external console :-)

Without external HDMI attached:
after switching radeon in kernel phase on EeePC 1015 LCD is text resolution set to 64 x 18 (and usable working with this resolution possible).

BTW: in both cases on begin booting (probably in kernel ACPI detection phase) goes the brightness of LCD to minimum. After login i am able to restore it with sysctl -w hw.acpi.acpiout0.brightness back to usable values.

FYI i send you complete file /var/log/messages attached. There are startups with and w/o external monitor saved. Weird: with attached HDMI is on probes of USB hubs an autodetection error enconutered. I dont know why...

IMHO there are simultaneously 2 issues on booting 10.1 in kernel phase - unseen to this days with NetBSD 8.x and 9.x:
a) snap-in to ACPI detection probably uses another routine (with newly resetting the brightness value to minimum);
b) switching the text resolution on radeon driver in kernel phase  another way, than NB8.x-9.x (previous versions manage switching to 120x33 (or possible more) w/o any problems).

I hope, my testing is usable to identify the problem source!
With regards
Radim
