Unless you've seen such reports yourself ...
I've had one report that the disabling of the "optimization"
causes problems. This problems seems to be a tricky bastard.

I applied this to 2.0.7, and it didn't work too well:

eth0: 3Com 3c590 Vortex 10Mbps at 0x6000, 00:a0:24:57:ee:81, IRQ 10
Internal config register is 120010, transceivers 0xe138.
8K byte-wide RAM 1:1 Rx:Tx split, 10Mbs AUI interface.
3c59x.c:v0.25 5/17/96 becker@cesdis.gsfc.nasa.gov
[...]

eth0: vortex_open() InternalConfig 00120010.
eth0: vortex_open() irq 10 media status 0800.

and about four minutes later:

eth0: Infinite loop in interrupt, status e011. Disabling functions
(78ee).
