Looks like this flash device can only be programmed with model-specific
registers (MSRs). On OpenBSD this is done via amdmsr(4) which requires
2 things: 1: it must be detected and attached in the kernel, and 2:
machdep.allowaperture must be set (normally on OpenBSD this device
is used for access to graphics with X).
If 1 fails you get ENXIO "Device not configured", if 2 fails you get
EPERM "Operation not permitted".
On your system the device does not attach (no amdmsr attach line in dmesg).
Looking at amdmsr_probe() in /sys/arch/i386/i386/amdmsr.c I see this
74 /* Check for AMD Geode LX CPU */
75 if (strcmp(cpu_vendor, "AuthenticAMD") == 0 && family == 0x5 &&
76 model == 0x0a) {
77 /* Check for graphics processor presence */
78 gld_msr_cap = rdmsr(GLX_CPU_GLD_MSR_CAP);
79 if (((gld_msr_cap >> 8) & 0x0fff) == GLX_CPU_DID) {
80 gld_msr_cap = rdmsr(GLX_GP_GLD_MSR_CAP);
81 if (((gld_msr_cap >> 8) & 0x0fff) == GLX_GP_DID)
82 return 1;
83 }
84 }

The family/model (05/0a) match but the driver is not attaching so it must be
failing the "Check for graphics processor presence" check.
If you were to remove that check, maybe it will work, or maybe it will
fail horribly and you will brick your board.
Personally I would recommend following pcengines' suggested procedure
and use their freedos image for alix.
