Yes, it has been reported already, and is most probably a concern in
VirtualBox itself, as qemu/kvm takes just a few seconds.

I guess you're thinking about the "probing eata" messages, which I added
precisely because VirtualBox takes eons to emulate it. This is

linux/src/drivers/scsi/eata.c:   printk("probing eata on %lx\n",
port_base);

It's the usual configure --enable/--disable.

€ ./configure --help | grep eata
  --enable-eata           Linux device driver for SCSI controller EATA
  --enable-eata_dma       Linux device driver for SCSI controller EATA-DMA
  --enable-eata_pio       Linux device driver for SCSI controller EATA-PIO
