Default OpenBSD 5.5 radeon/radeondrm cannot scroll framebuffer

This has bugged me for a while now and I've not managed to find any solution nor anyone reporting the same problem. Since moving to 5.5 the radeondrm framebuffer console has been in use by default. Now the console can no longer be scrolled up and down using Shift+Page Up/Down.

I rebooted and entered boot -c, then "disable radeondrm" which also disables the framebuffer console and gives "normal size" text, but then of course x.org won't start without the kernel mode setting driver.

Code:
radeondrm0 at pci1 dev 0 function 0 "ATI Radeon HD 3650" rev 0x00
drm0 at radeondrm0
radeondrm0: msi
radeondrm0: VRAM: 512M 0x0000000000000000 - 0x000000001FFFFFFF (512M used)
radeondrm0: GTT: 512M 0x0000000020000000 - 0x000000003FFFFFFF
radeondrm0: 1600x900
wsdisplay0 at radeondrm0 mux 1: console (std, vt100 emulation), using wskbd0
Anyone else had this problem?

Running 5.5 amd64 patched with
Code:

drm0 at radeondrm0
radeondrm0: msi
radeondrm0: VRAM: 256M 0x0000000000000000 - 0x000000000FFFFFFF (256M used)
radeondrm0: GTT: 512M 0x0000000010000000 - 0x000000002FFFFFFF
drm: enabling PCIE gen 2 link speeds, disable with radeon.pcie_gen2=0
radeondrm0: 1440x900
I also do not have Shif+Page Up/Down in the KMS console. Paging works fine in x11/rxvt-unicode though.

I did have a significant delay in the kms driver starting during boot after a patch. It resolved after I ran
Code:
./MAKEDEV all
in /etc

FAQ 7.3 states (highlight mine):
Quote:
The default scrollback buffer, or the number of pages that you can move up and view, is 8. This is a feature of the vga(4) driver, so it will not work without a VGA card on any platform (many Alpha systems have TGA video), or on hardware that uses drm(4)....Users needing this functionality may wish to use tmux instead, which provides scroll back and many other functions on all platforms.

Thanks for the replies.

I must have missed that part in the FAQ...

I will look into tmux later on. At the moment I've just reinstalled (on a SATA drive, was on a PATA drive before), so just need to restore my backed up dot files and get up and running again.

The tmux terminal multiplexor has a man page, which is very good. But there's also a quick start guide for it its own FAQ section: 7.9. I use tmux constantly, inside or outside of X.
