ok, 2.6 confirms that there is a problem with 80 characters limit:
...

obp_devread(fd 0xffd9e740, buf 0xe110, nbytes 8192) = 8192
obp_devseek(fd 0xffd9e740, hi 0, lo 15065088) = 0
obp_devread(fd 0xffd9e740, buf 0xe110, nbytes 8192) = 8192
obp_devclose(0xffd9e740) = 1
obp_fortheval_v2( ['] find-device catch if 2drop true else
current-device device-end then swap l!)
Unhandled Exception 0x00000007
PC = 0xffd05580 NPC = 0xffd05024
Stopping execution

2.5.1 :

obp_devread(fd 0xffd9eb94, buf 0xf00a0778, nbytes 8192) = 8192
obp_devseek(fd 0xffd9eb94, hi 0, lo 275275776) = 0
obp_devread(fd 0xffd9eb94, buf 0xf00a2778, nbytes 8192) = 8192
obp_devseek(fd 0xffd9eb94, hi 0, lo 275283968) = 0
obp_devread(fd 0xffd9eb94, buf 0xf00a4778, nbytes 8192) = 8192
obp_devseek(fd 0xffd9eb94, hi 0, lo 275292160) = 0
obp_devread(fd 0xffd9eb94, buf 0xf00a6778, nbytes 8192) = 8192
obp_devseek(fd 0xffd9eb94, hi 0, lo 275316736) = 0
obp_devread(fd 0xffd9eb94, buf 0xf00a8778, nbytes 8192) = 8192
obp_devseek(fd 0xffd9eb94, hi 0, lo 275324928) = 0
obp_devread(fd 0xffd9eb94, buf 0xf00aa778, nbytes 8192) = 8192
obp_devseek(fd 0xffd9eb94, hi 0, lo 275333120) = 0
obp_devread(fd 0xffd9eb94, buf 0xf00ac778, nbytes 8192) = 8192

And then it just hangs. I don't see the "krtld: error during initial
load/link phase" message.
