em resource allocation fails on SunFire X4500

[rondzierwa at comcast.net]

I am using 10.1-RELEASE on a SunFire X4500 (thumper). It has 4 em devices, of which only the first two work due to a resource failure: 

em0: <Intel(R) PRO/1000 Legacy Network Connection 1.0.6> port 0xcc00-0xcc3f mem 0xfdae0000-0xfdafffff irq 52 at device 1.0 on pci7 
em0: Ethernet address: 00:14:4f:21:09:94 
em1: <Intel(R) PRO/1000 Legacy Network Connection 1.0.6> port 0xc800-0xc83f mem 0xfdac0000-0xfdadffff irq 53 at device 1.1 on pci7 
em1: Ethernet address: 00:14:4f:21:09:95 
em2: <Intel(R) PRO/1000 Legacy Network Connection 1.0.6> mem 0xfdbe0000-0xfdbfffff irq 61 at device 1.0 on pci8 
em2: 0x40 bytes of rid 0x20 res 4 failed (0, 0xffffffffffffffff). 
em2: Unable to allocate bus resource: ioport 
em2: Allocation of PCI resources failed 
em2: <Intel(R) PRO/1000 Legacy Network Connection 1.0.6> mem 0xfdbc0000-0xfdbdffff irq 62 at device 1.1 on pci8 
em2: 0x40 bytes of rid 0x20 res 4 failed (0, 0xffffffffffffffff). 
em2: Unable to allocate bus resource: ioport 
em2: Allocation of PCI resources failed 

a previous bug, #196501 was closed by setting 'hint.agp.0.disabled=1' in loader.conf, but this had no effect on the X4500. 

I have attached the pciconf output. 

Thanks in advance for any help or suggestions!
