What adapter are you using?
What module are you using?
How are you trying to enter promisc mode?
Do you get an error, if so what does it say?

I have intel epro100, and i use e100.o module from intel. When i had redhat, it works, but now, it doesn't. I enter promiscuous mode: ifconfig eth0 promisc, and then with ifconfig -a i see PROMISC mode activated, but gkrellm or another network monitor doesn't show anything, while my friends are downloading. |

I run gkrellm with the network monitor, and it is blinking at me right now, but ifconfig doesn't show promiscuous mode enabled. When I run snort -v on my box dmesg shows "device eth0 entered promiscuous mode," but ifconfig doesn't show anything about it. Snort works as expected too. When I stop snort it shows "device eth0 left promiscuous mode."
This leads me to look at your network module. Did you use the same module in RedHat? Does tcpdump work at all for you?

I decided installing tcpdump in order to test the promisc mode, but i get this errors:
gcc -O2 -march=i686 -O3 -pipe -I. -DHAVE_CONFIG_H -c ./bpf_dump.c
flex -Ppcap_ -t scanner.l > $$.scanner.c; mv $$.scanner.c scanner.c
bison -y -p pcap_ -d grammar.y
make: *** [grammar.c] Segmentation fault
make: *** Se espera a que terminen otras tareas....
gcc -O2 -march=i686 -O3 -pipe -I. -DHAVE_CONFIG_H -c bpf_filter.c
bison -y -p pcap_ -d grammar.y
make: *** [grammar.c] Segmentation fault
!!! ERROR: The ebuild did not complete successfully.
!!! Function src_compile, Line -88, Exitcode 2

make is segfaulting, that's not good. What are your CFLAGS?
