    Yes I did. Unfortunately difference between 5.1 and 5.2.1 is just too big:
 http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/bge/if_bge.c.diff?f=h&r1=1.41&r2=1.60
    With 5.2.1-p9 sources when I replace if_bge.c rev. 1.60 (5_2_1_RELEASE) 
 with rev. 1.41 (5_1_0_RELEASE) kernel would not compile at all:
 
 /usr/src/sys/dev/bge/if_bge.c:107:24: pci/pcireg.h: No such file or directory
 /usr/src/sys/dev/bge/if_bge.c:108:24: pci/pcivar.h: No such file or directory
 mkdep: compile failed
 *** Error code 1
 
 Thanks,
