Broadcom NIC compatibility problem with update 4

With RHEL ES 4 update 4 on an HP ML 370 G3 with a Broadcom
gigabit NIC, 
the system cannot get the Ethernet address for the NIC and
the rest of 
the init of the NIC fails subsequently.
This problem happens once out of two reboots. Boot once, it
works, 
reboot, doesn't work. The LAN is the same, hardware is the
same, 
software is the same.
In dmesg, I can find the following for the problem boot:
 > tg3: Could not obtain valid ethernet address,
aborting.
 > tg3: probe of 0000:01:04.0 failed with error -22
And this for the OK boot:
< divert: allocating divert_blk for eth0
< eth0: Tigon3 [partno(TBD) rev 1002 PHY(5703)]
(PCI:66MHz:64-bit) 
10/100/1000BaseT Ethernet 00:0b:cd:e6:4e:a0
< eth0: RXcsums[1] LinkChgREG[0] MIirq[0] ASF[0] Split[0]
WireSpeed[1] 
TSOcap[1]
< eth0: dma_rwctrl[763f0000]
< ip_tables: (C) 2000-2002 Netfilter core team
< tg3: eth0: Link is up at 100 Mbps, full duplex.
< tg3: eth0: Flow control is on for TX and on for RX.
< eth0: no IPv6 routers present
Result of lspci for the NIC is:
01:04.0 Ethernet controller: Broadcom Corporation NetXtreme
BCM5703X 
Gigabit Ethernet (rev 02)
There is a difference in the result of lspci -nv though:

The busmaster and latency 64 flags are absent when the NIC
init fails.
The BIOS version is the last one from HP, P28.
System was OK with RHEL ES 4 updates 1 thru 3.
